Anyone played Battlefield 1492, er 1943?
I downloaded the demo, then immediately bought the full version. I think it's well worth the 15 bucks. It's kind of a simplified version of 1942. Only 3 classes, 3 maps (a 4th is coming out), unlimited ammo. It's got jeeps, a couple kinds of tanks, boats, and planes. There are no bombers that you can get in, but there is an "air raid" mode where you guide the bombers to the target and release the bombs.
I don't expect it to keep me entertained for more than a couple weeks, but it's a total blast right now!
