Okay so I wanna crowdsource this shit.
For DBZA mafia I'm considering integrating a power levelish mechanic. It'd be some sort of mix of LP and Power from Lotus's game, but it would in no way affect lynching. Krillin's lynch will be worth as much as Goku's, and if you hit a majority, you die no matter who's lynched you. Any increases in Power Level are on a set track. Most roles will have some sort of fight mechanic. You're not likely to die if you pick a bad target. I mean, I haven't worked out the specifics, but maybe a Yamcha vs Vegeta thing would go pretty badly. If Piccolo and Gohan wind up fighting by accident, they won't waste each other at the expense of the town. Keep in mind that targeting one way is different than the other. Decking Freeza won't kill you. Probably. But if Freeza's coming after you, then you're probably fucked. Alternatively, Power Levels will act as a sort of resistance thing. Or something. idk suggestions would be nice.
Then Xiaolin Showdown, of course, would not be complete without actual Showdowns. Best idea I have atm is that each character will have set stats D&D style. Dex, Str, Wis, Int or so. Each showdown would be a random test of one of these stats. Various characters would get a starting Shen Gong Wu, and the rest would show up in stages. Individuals can hold a max of two, and mafia can only have like two extras total I'm thinking. The Wu would be the providers of the night/day actions/effects, and would do some sort of stat boosts for the Showdowns. So the Fist of Tebigong will punch the shit out of people, while also giving a Strength bonus.
idk. I may think of better ideas later but this is where I'm at.
