@beadsland Well, for example GURPS Has several core balance assumptions - character points will be had to come by, you can't have traits that let you self improve or that pay out constant benefit, no absolute immunities or defenses, etc. These are usually good ideas, but I'd like to have guidelines in place for GM when they want to not use them. Also have guidelines for changing the length of a turn, changing mechanics or stats depending on whats important for your game, etc. Not sure these are actually cool ideas, but it would be fun to experiment with them.
