Like a lot of referees who've played around with multiple editions, I use so many house rules that it's almost a different game (mechanically speaking at least). I designed a player reference that fits everything my new players need to get started on the back of the character sheet I give them. Download here.

This is meant to be all you would need to jump into your first game as quickly as possible, but doesn't include things like level progression. Those are all scribbled on random pieces of paper on and around my desk at the moment. Eventually I'm going to pull together some sort of reference for things that won't come up for most players until a couple sessions in. Probably.
