I had no problems unlocking the avatar awards or gamerpictures, nor did I encounter any game-breaking glitches or bugs. For a game with easy achievements, okay gameplay, avatar awards, and a price of 160 Microsoft Points, it was considered a steal.
Now that it's priced at 800 Microsoft Points, though, I don't think it's worth it. Unless you prefer button-mashing games with mediocre humor or if you're a complete avatar awards junkie.
