My new lady friend loves to play video games (she's hot too, honest). So, we have been logging a lot of time in on the games lately.
Twisted Metal Black
Sure, it's a few years old, but this game is by far the best car combat game I have ever played. I'll leave Mario-Kart for the kiddies, thanks. Dark, atmospheric, tone combined with a great controls, amazing level design, and a slew of fun to use weapons. Also, I got the game for under 10 bucks. Sorry, you just can't beat that.
We also recently went through Resident Evil 4, which still totally rocks.
John listed a Shin Megami Tensei game above. I must again chime in on the cool design aspects these games have. Check out one of these titles soon, folks!
My lil lady is also going through GTA: San Andreas. I had already beat this game, and I am now constantly impressed with how differently her game is developing when compared to my first run through. Fun stuff. I will say though, some of my other games, like God of War, have aged pretty well as far as graphics are concerned, but, GTA is looking pretty rough these days...
