Seriously though, the phrase "it's just a game." You know what, next time you say that I'll belittle something you care about. A game is competition, it's about triumphing against your enemy: is it so wrong to care about it?
Also, I hate people who just shake their head when I say games are a form of artistic storytelling. I don't see how it's so hard to understand: regardless of their previous experience, is it so hard to understand that it's possible for games to tell a story? It annoys the crap out of me when someone is so blind they can't even see the validity in that claim.
