I never had a lot of standards with my games, my biggest thing was that everyone have fun and cooperate. It wasn't until I moved away from D&D that I finally managed to get that. Most of my D&D players just couldn't cooperate and because of that I hate D&D, well that and the fact I always had to be DM.
As long as my players are having fun, then it's a good session. (this isn't counting forum RP, I very rarely do that, and don't really enjoy it)
