I love the game and it works perfectly for me. I don't know if it is coincedence or not, but I found out the game doesn't work for me unless I have the gamefly client app open and running in the background. So for those of you who are having problems getting the game to play, try running the gamefly app in the background then play the game from there. It works for me and I LOVE THIS GAME!!!! It has good game play and an excellent storyline.
As an avid player of both Abe's oddysey and exoddus when they released, I can confidently say this is a great additon to the series, the humor, voice acting, and well, everything from the first two is there and more.
My only complaints are the default controls (Raghh!) and the camera can (occasionally) be goofy, but it was released for xbox in 2001 so, really, who cares just change them via menu and such.
I suggest standard WASD movement with [numpad zero, numpad period, and numpad enter] as your weapon, action, and chant. (vice versa for south paw) leaving the default camera as moving the mouse for when it does goof up. Or whatever suits you.
Hope it was helpful.
