Shadow Complex is a video game based off of a Card Book (not in the Ender series and not named Shadow complex... can't remember the real name) about a group of liberal terrorists. In the game, they didn't bother to explain the political affiliations of the terrorist, they're just bad and you kill them, but there was still controversy and boycotts surrounding the game because it a) was based off a very conservative novel and b) some portion of the money you spent on the game theoretically went to Card which could theoretically be spent on anti-gay propaganda.
I didn't buy the game simply because I didn't feel like it (I still periodically buy Card's books even if I don't agree with his views... if I wanted to boycott stuff I'd start with a lot of much worse things).
