I don't know what kind of character to plan for. It's really hard for me to figure out what to do in games, nowadays.
I've got anti-hero ideas, intellectual ideas, and idealist ideas. For this game, I want to go with a cowboy assassin, but I also want to be a passive scientist with energy weapons as a fallback. The problem tends to be that I'll roll one up, then start playing as the other halfway through.
I guess what I'm saying is that I want a multiple personality trait. Pick two distinct character builds, but the game randomly determines which one is available at any given time!
