I'll be honest, I've wondered this myself. I feel a lot of it ultimately comes down to trust. The writer trusts that the GM, whoever they will be, will get it "right", where "right" is what is most entertaining for the group they're GMing for. There are a LOT of variables; what the GM and the players are comfortable with, what kind of game they're looking for, how familliar they are with the tropes, conventions and ideas the game is pushing, etc.

I would suggest looking at the powers not as Moves in an of themselves, but rather something that you can act through; a tool that expands what you could do.

Take Laser Beam Eyes. You could come up with a couple of custom moves for it, but ultimately, it's what the player wants to do with it that will engender rolls or not. Same with flight, or super strength or any other power. By itself, it just happens, no need to roll. It's like walking, or making a sandwich. Now, in a dangerous situation, when the stakes are high, when there is a chance of failure? Yeah, there's going to be a roll, but it won't be a Super Strength roll, it'll be a standard Move that was made possible because you have super strength.

As a suggestion (just spitballing here), you could do something like have each super power be a Stat. If you use your super power to perform a Move, instead of rolling a Move using your normal stats, you roll using your super stat, kinda thing.

So, in short, we had a fuckin' blast with it. I think a large part of it for the group was just being able to play something that wasn't DnD, and particularly something that was kind of Firefly-ish.

We had:

An Artificial Military/Personality who was a mercenary with a Squad, who was the original owner of the ship itself.

An Artificial Scoundrel/Cybernetic on the run from the Imperial Navy R&D project that created him.

And a Spacer Clandestine/Starfarer, who was a little more amorphous, but had a background with the Silver Syndicate, a galactic trade cartel/migrant fleet. Kind of a schmoozer and a blockade runner, the kind of guy who can talk his way past a roadblock or a star-system interdiction with equal ease.

We kind of skimmed over the crunchy mechanics of the ship and stuck to the feel of it. Ship-to-ship combat was avoided when the Captain used his Gadget for a decoy system and maxed his Avert Disaster roll, thus escaping the Imperial Naval Intelligence ship that was trying to run them down. Looking back, I probably would have made him take a debt and then fight a boarding action; he should have won it easily, since the Agents wouldn't have been expecting six highly trained Marines and a couple of supersoldiers to be their adversaries.

Character creation took about two hours between three players, which I didn't find surprising since we were handing off between two computers and two of the guys had never played an AW type game. That done, we spent at least as long on actual gameplay, in which we did a lot of world-building and fleshing out of our characters.

This was my third time GMing, and the first two were using straight AW. Third time was the charm for a successful and fun session on my watch, since the last two kind of flopped due to group chemistry and some lack of understanding on everyone's part. I think it might be the comparability of settings; when you compare AW to Mad Max, people look for the Humongous or Barter Town. When you say Firefly and Mass Effect, people want to walk around, meet people, and pull of a heist or two.

Seeing as how it was my third game ever as a GM, it was nice for my players, instead of asking what other systems I could pitch, to say "We're doing this again next week, right?" Really glad I went with this over the FFG Rogue Trader.

tl;dr It's solid, newb friendly, just needs the finishing touches put on it. Character advancement, ships and ship combat, and a sheet is all it needs. Moves need a few tweaks, or maybe some adds. There's no equivalent to either Go Aggro or Seize By Force, which my players needed a few times. Also, maybe an Interrogate move? But as I said, there's no reason it can't be played as is, unless you really need the stats on that ship.

Fantastic, I'm super happy it worked well. Thanks so much for playtesting and giving feedback, it does my poor, fragile ego good to know that people are having fun with it. I've done a pretty major pass over some rules, Weapons, Armor and Harm, making combat more narrative, descriptive and fast-paced, and less numerical. Ship creation and combat is coming soon, I hope to deploy that at the end of the month along with a revamped crew/squad rules.

In the meantime, here's a link to Uncharted Worlds v 0.5.4 with the new combat rules.

0.5.4 Changelist Changed Step 1 of Faction creation Changed Open Fire move Changed Launch Assault move Added Suffer Harm move Changed Harm rules Removed Health/Wounds rules Changed Armor rules Changed Weapons rules Changed following skills: Hacking (Scientific, High-Tech) - Replaces "Calibrations" Calibrations (Starfarer) - Replaces "Spaceworthy" Heavy Lifting (Military, Spacer) - Replaces "Armored" Special Ammo (Military) - Replaces "Weaponry" Toughness (Military, Frontier) Scrappy (Scoundrel, Frontier) Survivalist (Explorer, Frontier) Harder (Cybernetic) Faster (Cybernetic) Stronger (Cybernetic) Interrogate (Clandestine) Fixed numerous tpyos

As for Seize by Force, that's handled by the new Open Fire and Launch Assault moves. Take a look and tell me what you think. Personally, I'm not a huge fan of "behavior control" Moves, though, so I'm still iffy about Go Aggro-style moves and even the current Manipulate. Those remains to be seen. I'm thinking that Avert Disaster using Influence might just cover cases where the dice are needed.

Thanks again for the feedback, really enjoyed your synopsis, and I'm looking forward to getting v0.6 (launch of the spaceship rules!) out the door airlock asap. If you have any questions about 0.5.4 (it's a pretty big change, combat-wise) please don't hesitate to ask. I'm afraid this site is blocked at work so I don't check it as often as I should, but if you want to get in touch with me, I'm also active over at Story Games. Heck, I'd be much obliged if you could repost your post there, too :)

Wooo! Grats Sage!

Thanks for the reply. I find the whole "what do tractor beams imply about warfare" angle super interesting! In a way, tractor beams are the melee combat and grapple to ranged combat of rockets and lasers. I can see focused tractor beams being used to tear hulls apart (which would also have uses in the asteroid mining and salvaging sectors). What's more, tractor beam and shield technology seem to come from similar ideas; creating fields to affect matter.

I also realize that with tractor beams comes much easier access boarding parties and raids, which is just too good to pass up.

Now to come up with a name for this technology. I was thinking just "kinetic", as in "Kinetic Shield", "Kinetic Net", "Kinetic Lance", because it makes close ship combat feel somewhat... gladiatorial? However, it being kinetic makes it rather useless against laser weaponry, yes?

Good questions/comments, Phaed, thanks for crossposting them (for those wondering, Phaedrus has been providing me feedback for a bit, so I asked him to hop on these forums to post his feedback here, seems like the right place for it)

I'll try to address them here:

- Scapegoat seems ripe for abuse.  Probably be better to make it an +Ing roll triggered by a 6-, rather than an automatic success

Note that it's the GM that chooses who your potential new targets are, and the player has to choose one from among them. In a game where the crew is your (dysfunctional) family and everyone has a faction behind them, inelegant use of this skill will trade short term ass-saving for long-term trouble. That said, it'll be something to keep an eye on in play.

- You get followers, you get followers, you get followers!  EVERYBODY GETS FOLLOWERS!  When one person can roll up 12 followers, you've got the makings of a bookkeeping nightmare and a huge ensemble cast.  I would at least make the followers skill only takable once.

Actually that's a conscious design decision. I wanted to capture the gang/holding mechanics from Apocalypse World, which I feel were missing from Dungeon World. It plays heavily into the idea of "crew as family", and gives a lot more opportunities for PC-NPC-PC relationships. Having people bound to your through duty or employment fits a number of the Principles of the game.

- With your current very strict debt/favor mechanic, "Investments" seems way overpowered.  Get an additional +3 favor when most others get only 1 +1, and replace a crushing, inescapable debt with one that can be worked off fairly easily?  Win.

Duly noted. Tweaking is undoubtedly in order

- On the same idea, equalize Authority/Diplomacy.  Either +/-3 or +/-2 would work, but +4 favor means you can ask for about anything and get it without penalty.  That should have a bit of cost.

Note that even on a 10+ with Acquisition, you still gain Debt. So far the only way to not gain Debt to someone on an Acquisition is to be a Criminal, Roll 10+ on your crime, and then roll 10+ on your Acquisition.

-Ice Cold doesn't make any sense without +cool.  I'd replace Mettle with Ingenuity and call it something like "schemer."

Hm, true. That definitely is a throwback to when Hot was the primary interaction stat. I'll look at "Outwit" or "Scheme" as a stat replacement, I just have to make sure there's an even distribution of stat replacements.

-Why does changing a melee weapon into an energy weapon add +Reload, but turning a missile weapon into an energy/laser weapon remove -Reload?

Laser ranged weapons have high-capacity batteries that you can fire hundreds of times before losing their charge, and can be easily plugged in to recharge. They don't have physical projectiles that need to be reloaded. While it's possible they may run out of charge during a prolonged fight (as a result of a 7-9 or 6-), they don't need to be reloaded regularly.
Energy melee weapons discharge their entire cell into a strike, and have to power up again after each contact. From a design standpoint, melee weapons do less damage than ranged weapons, but don't require reloading, while guns deal more damage but do require reloading. You can alter your melee weapon to hurt more, but at a cost (making large and 2-handed or making it require recharge time between strikes).

-What does 2x Loud do?  (Pistol/Rifle+explosive)

It's very, very loud. Like really loud.
[edit] also it means you can't have a Silenced Explosive gun.

I guess a bit of information about the game is in order, eh?
