BarbieZero: Thanks everyone for all the help. Many will be sad to learn I love Apocalypse, Zombies, Possibly ArmA if I could ever get the controls down. War and bloody savagery. I'm better at reading. But I run out of books and my own mental imagery runs dry. So... games.
And I like Baldurs Gate and Dark Alliance
Give Fallout a try -- it's like Baldur's Gate in an apocalypse setting. Of course, you need to get it on Steam b/c GOG just lost rights for it a month or two ago (the game rights switched hands to Bethesda).
If you'd like a more combat-centric Baldur's Gate, Icewind Dale is a great game.
Neverwinter Nights has zombies, but they're rather lame. Nonetheless, it's the next step after Baldur's Gate in the Bioware RPGs.
You might also like to give the Spiderweb games a try (I'd start with Avadon: The Black Fortress, personally). They are like reading a book and playing a game at the same time.
As for war and killing, Rainbow Six and Splinter Cell are spectacular sneaky games. And, though I have a hard time saying it's worth $6, Zombie Shooter has a very nice blood-all-over-the-place-kill-as-much-as-possible feel as any game I've ever played.
Also, I'd recommend taking a look at the top sellers. They're almost always a great game.
