It needs to be fairly balanced in terms of mediums and character age range or I don't even bother digging deeper into the game. I like a good mix of drawn mediums+LA+vidya, and because most of my active characters are over 25/30 and I'm not interested in RPing babysitting, I need other adults to interact with. Doesn't really matter if there's large casts in the game. Chances are slim I'd have any castmates myself.
