I already own the 360 version to take advantage of the two expansion packs but I only paid $20 for the PC version a couple of weeks ago. Wish I hadn't though, the PC version keeps crashing me to the desktop after playing a few minutes at a time. I have the latest patch for the game and Windows Gaming Live. To me it appears there is a serious memory leak in the game. I don't get an error message, just get dumped back to the desktop everytime. This does this too me in XP, Vista and also the new Windows 7.
