Now that I've had a chance to take a closer look at the rules, I wanted to chime in to offer a suggestion that I hope is helpful and not obnoxious. Namely, I feel like there's still room for "weird" (instead of will) in Mass Effect, and I've given some thought to how I could hack your hack to shoehorn that in for myself (and anybody else who's interested).
Maybe Ardhanari can comment on the intent behind "will" (I may just be missing it), but I am getting stuck in two places with this stat. First, it's not clear to me what it accomplishes that hard and cool weren't already doing. And second, it reads more like a classic "what you can do" stat (in the D&D vein of STR, DEX, CON, etc.) than a "what you are like" stat (in the vein of Apocalypse World, where the stats are otherwise all adjectives describing personality characteristics). And, as a side effect of that second point, this means that we lose an entire dimension of "what you are like" that is kind of important for describing certain kinds of characters in this universe.
"Weird" in Mass Effect is not exactly the same as "weird" in Apocalypse World. In AW, it's most obviously associated with uncanny powers and the psychic maelstrom. In ME, on the other hand, all the "psychic" stuff is actually fairly mundane (explained through sciences related to biotics, asari physiology, etc.). Nevertheless, weirdness is still really central to the tone of a lot of the ME games.
A character who's really good at biotics should probably still have high cool or hard scores rather than a high weird score. A character who's got a really high weird score, however, might be...
- a colonist with psychic after-effects following mind control by a hyperintelligent plant;
- a scientist who has started to go mad after studying the artifacts of a race of spaceship elder gods;
- or even a salarian who thinks and speaks so quickly that other species (and some of his own species) simply can't follow him.
If it helps you to think about it, the "weird" stat in ME could probably just as easily be called "alien." It's basically that which is so strange and foreign that the mind reels trying to grasp it.
Weird still deserves a basic move, but "open your mind" doesn't really apply in this setting. I'd be curious what you think would be appropriate, Ardhanari (and what others think here), but I'm thinking I might start with something like, "When you confront something you never could have imagined...."
All of that said, thanks again for producing this hack, and great job translating so many Mass Effect terms and concepts. (I was really pleased to see Paragon, Renegade, and Fitness still find their way in there.) My fiancee has never even played Mass Effect, but she was super excited by your rule book. She's seen me play so much that I think she sees this as a chance to finally get her hands on it without developing shooter skills. I support this!
