I noticed this myself. It's a bit odd that Super Mario Galaxy (released in 2007) and Super Mario Galaxy 2 (released in 2010) are both $49.99 and sit right next to each other on the shelf. I remember seeing another game (forget the title) that was also $50 and came out in 2006. An equivalent game on the 360 or PS3 would be $19.99 or even cheaper by now.
