It's not a bad game if this type of game is your type. Cheapest on eBay is currently going for about AU$50.00 so I think this is not a bad deal at all. This is the Asian version but is playable on all region XBOX360s. Shipping is only a few bucks as well which isn't bad.

Good deal, last two Tomb Raiders haven't been bad at all. Just wish I had more time to play them.
