Americans officially have no right to complain about the price of GH or RB. Here in the UK it costs £150 for GH:WT - thats almost $300. For one game. RB costs about $30 less, but only because it's been out longer and some retailers have cut it's price a bit.
PS3s here are $580 - the cheapest they have ever been, and PS3 games are $80, Wii games are $70.
Really, you guys are very lucky.
