You guys say this as if everyone here has a PS3, which isn't true, of course.
For non-PS3 owners or those with a 360, this is a good deal. Walmart had it for $8 shortly after the holidays. A solid game experience. Short (like a good popcorn movie) and no replay value (like a good popcorn movie).
Easily the best on-rails shooter I've played since Time Crisis 3 and Panzer-Dragoon Orta.
