These prices don't seem cheap enough considering how bad this game is. I really enjoyed the previous game in the series, but this one stunk. The first 20 minutes are pretty fun, then it turns into a monotonous, linear trek through lots of small corridors, shooting wave after wave of identical enemies (usually monsters). Maybe it gets better later on, but I couldn't take it any more.
Plus, this has been $5 a couple of times for the PC. Different platform, I know, but a far more appropriate price for what you're getting.
