On Tribes 2, we have been playing the same damn map for 2 years.
Let me guess: Katabatic?

Anways, I'd recommend CoD too. It's great fun, though a bit short. And there's a great (though not widely played) mod called www.heatofbattle.net (think DoD)

HL2 is also fun (nothing like killing another player with a toilet!).

Have you tried Mount and Blade? It's real good.
