I am going to throw in a vote for UT2k3. It's a great game that is starting to get a good mod community behind it. So there will always be something new about the game. If I had to choose a new hottest game, I would go with Enter The Matrix. It is just a cool game. I am blown away by what all you can do in this game. If you don't want to run around shooting people, let your hands and feet do the talking.

*votes for BF1942*
Go with BF, although most servers are filled with llamas, it's the only game that hasn't got boring to me.
UT2k3, great, looks nice, and is fun for about 1hr.
DF black hawk down, again looks nice, but that's about it.
I thought rainbowsix3 had a longer lasting appeal compared to DFBHD though.
MOHAA is ok, you could go with that i guess.
AVP, something about all the AVP series never made the game 'feel right'... there was just something odd about it, but it had some cool ideas.
I would go with MOHAA for the singel player mode. If you're looking for multi-player then Battlefield 1942 would be my choice. Unreal 2003 is good also as long as foul language (whatever that is) isn't a concern.
