[quote name='jlarlee']$10 for the ps2 version at mine[/QUOTE]
That's how I got mine a few months ago. Finally getting around to playing it now, and I'm really enjoying this game. I'd say it's worth the $20 price tag.
If you have a choice, get the Xbox version for $20. The PS2 version is inferior in every way.
It's a great game, though. I'm kind of spoiled by Nintendo, so I set my platformer standards pretty high. If anything, it's very quirky, something that Nintendo wouldn't touch.
If you can't get it at gamerush you can check BB to see if it has dropped to $19.99. If it has dropped then use the GGC to get an extr $5 off making it $14.99. This title reminds me of BG&E, innovative and fun game, but the overall gaming community still finds it hard to take a chance on an original title.
