Man, Into the Odd was/is so good. Hyper fast setup: 3d6 three times, then 1d6 for hit points. Consult the chart 'n' off you go, with some interesting and balanced (in a way) weirdos. I wish 5e could be that quick and simple.
Well, you know what? It can be!I dont have Electric Bastionland, or ItO Remastered, or more current iterations of the thing but I do have the waaaaay back ItO , and the early one with the red cover. That is not to say you shouldn't go get those new things, but this is a remainder from the Geeplus days of ItO and has wormed around in my moth-eaten brain for some time. I haven't tried it as such, but it's sprouting now and if radical alteration of the fundamentals of games is not your thing, then probably move along now. I'm ripping it from the Red Cover version down below.
So: You roll 3d6 three times and 1d6 for starting hit points (or 4d4 if you want the median to move up a little bit at the expense of headroom). You put those where you want them. The rest of your stats are 8. Yes, 8. These are 0-level dorkusses. The background will be "Oddball Novitiate" or something like that. Don't apply racial bonuses or abilities just yet. You don't get the rest of the stuff you might otherwise get, either. Save that for after your first mini adventure. Consult the chart (I hope Chris and Paolo don't mind I screen capped it - I purposely kept the resolution pretty low). Where it says 'Arcana', for the really low powered folks, you get a totally-randomly-generated magic item, up to and including Earth-Shaking unique artifacts. ImHO a level-0 with the Hand of Vecna would be awesome, and a perfect candidate for all sorts of shenanigans. Balance and fairness be damned. You can get 1d6 times 10 gold pieces, too. As a treat. for rations and candles or whatever. Then, you get dropped full on into some precarious situation. Maybe your skyship is caught an a mountain peak and you need to get into the town below for supplies (actually happened in a ItO game I ran back in the day)
Weapons do the appropriate amount of damage and types, and firearms can do either Blunt or Radiant or Fire or whatever as you like, since they could be laser guns, too in my game.
Taaadaaaa! Fast and furious - off you go and stay in trouble, kids!
