Although I like Battlefield 1942 alot, I've recently purchased slitherine Software's "Spartan". It's quickly become my favorite. Sure there are action sequences but the strategy is far more the thing. This game is aimed right at folks like myself who are looking for something more along adult lines of game play than blowing things to kingdom come. I started a thread about it in the Internet Gaming forum awhile ago. You can check the game out here:

I think I'm going to buy their "Gates of Troy" game next and see if it takes place in Britain or not bwa ha ha ha!

BlackHawk Down All the way and Joint Operations

Rome Total War and Call of Duty

I'm sorry but it is all about Rome: Total War

Battlefield 1942 Desert Combat mod, just for the pure fun of it. I can't wait until Battlefield 2 comes out.

call of booty....uh....i mean duty.

but i'm pretty sure that battlefield two will replace it!~

Hidden and dangerous 2

Steel Panthers: World at war II

Delta Force: Black Hawk Down

I love the first and second Red Alert and RA Aftermath, However I was disappointed in the Yuri's Revenge plot the only perk to it is that you get SEALs in multiplayer.
And Delta Force Two is Hard Core

I used to love "America's Army" but now I like "Counter Strike: Source" more
