It's up to you. You're allowed to read/play/watch whatever you want, don't let us internet weirdos (who might not even be real people) dissuade you. My wife loves harry potter but hates Rowling's politics. That's ok. You don't have to justify your actions to anyone, least of all internet strangers! If you want a justification to play the game, as others have said, she's already made her money from the game and won't make more directly from you playing it, so she doesn't benefit. Also, by a few accounts I've heard it's a pretty mediocre game, so don't feel like you're missing out if you decide not to!
