You don't have to be gay to play and enjoy games with gay characters, protagonists or plotlines. I'm not a psychic space marine but I enjoy System Shock 2. I am not a blob of mucus but I had fun in World of Goo. I play games for fun, stories, new experiences. If I had to play myself all the time (like in real life) I'd soon get bored. My stats are rubbish, and I'd be playing a game where I spend most of my time staring at a screen. :-)
