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 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 :rambo:
