Are you willing to be a DM or GM, or just a player?
Both, though my tastes as a GM and player are different.
As a player I'm a method actor...I like to know what makes my character tick and I like to stay true to the character. My playstyle is high risk/high reward, so I like games that fit that approach.
As a GM, my games embrace chaotic, horrific, dark, humorous, morally ambiguous and violent stories, with a strong pulp feel.
My focus is on creating a setting and backstory which the players then react to, and the ensuing chaos shapes the story. I prefer this to be fairly freeform and will dismiss rules and the system if it gets in the way of the tale.
So..if you're looking for realism, solid tactical play, adherence to rules (also scripts, canon or metaplot) or resource management then you'd be better served by another GM.
