Hi everyone I just ran my first dungeon world one off yesterday and came up with a glaring problem. Any tips on how to curb player sillyness when fleshing out the setting and the lore. Two of the players I was playing with just seemed to want to create the silliest setting they could come up with and as a GM it's a little disheartening. Should I ask less open questions at the start or should there be a house rule to help curb stupid things like a bard singing 80's rock anthems to calm a banshee. Yes that was one of them. Or the many tentacled naked woman which was another. It was a terrible experience and the other two players weren't enjoying it because it was like the first two were just trolling the game. I tried to get it back on track by using loaded questions but the damage was done.

I am going to run another one off next week however but I'd like tips on how to stop this. I guess it's my failing as a GM so some tips would be great, especially for starting off a one shot and getting it on the right track or at least sticking to a less ridiculous theme.

 Another problem I'm having is just with starting gold. I noticed only a few classes get starting gold and it's a choice. Should I give them a small amount each or should I just stick with what the classes state?
