Excellent stuff. More games please.
Also, missed opportunity to make the G in Get fucked bigger and rounder so it the whole phrase resembles a cock and balls.
You really don't need to. You can do those things using the existing skill system if you need to. Just make a 3d6 roll under the difficulty you decide (i.e., for checking if they know stuff: 17 for common knowledge, 12-4 for less well known stuff, 6-8 for very esoteric subjects).
Or you could just give them the information because it's more fun.
This game is Rad (please don't hate me). Shades of Fallout, Stalker, Metro 2066 and probably a bunch of other things I'm missing. But this game is more than just its aesthetics. I have a few friends who I know will love this game and its evocative setting very much.
Get this now, you won't regret it.
