You're only going to get a lighter RPG than this if you go for a one page rules system (like Lasers and Feelings for example). This game doesn't even have attack rolls; all attacks automatically hit and do damage, making this a pretty lethal system. There are also plenty of hacks of this game (horror, sci-fi, etc), giving you plenty of flavors to choose from.
This is excellent. Well written, concise, and - yes, as odd as it needs to be, but it all makes so much sense in my head. This could become my go-to rules light RPG. I like the new layout and the collage-style art.
