Hey Sean,
If you want to try out Titan Quest and get a feel for the gameplay, here's a link to the official demo (500 meg download):

You can get a good feel for the game using that demo. I think you'll find that the gameplay is almost exactly identical to Diablo II, but slightly better. The graphics are extremely detailed, and the game is a huge resource hog, but if your computer can run it, it's definitely worth getting.
