One of the best rentals I've ever bought. The reviews were all sorts of fucked up though; for all the talk about how the game reinvents this or revolutionizes that, I was surprised to find a very pretty but rather basic first person game that failed to go beyond, and in some cases even measure up to, the legacy set by the developer itself, and also Ion Storm's Deus Ex. I'd call it a masterpiece in its own right though, but not for all the reasons most commonly cited by game critics who seemingly began playing games in 2001.
