There is likely no game that I've spent as much time playing online as Battlefield: 1942. The Battlefield formula is great - team-based multiplayer combat centered around attacking and defending certain locations. I've really enjoyed the latest in the series, Battlefield: Bad Company, but I'm quite excited about the newly announced Battlefield: 1943, which will be an Xbox Live Arcade title this summer, updating some of the classic Battlefield maps with the new technology of the Frostbite engine. Looks like it should be a blast (no pun intended). Here's the trailer.
