I've heard all the lines, most of them different spins on the old questions, "if you like these games so much, why don't you learn to play an instrument for real?" Well that's an easy answer: I know how, and this is still fun. I can't sit at my drum set and have my friends able to sing along or play a guitar with me. They're good party games, alright? Lighten up.
