God of War is the best game out of that list and is a must-play if you like action games, as far as I'm concerned. However, Resistance 3 is also a really good game that I'd like to see more people play, so I voted that.
Assassin's Creed 2 is also worth playing if you've never played any of the other games, but I've kinda shied away from that series after it supposedly went downhill and never played 2 all that much. Driver San Francisco has a good idea that apparently works pretty well, though I haven't played much of it so I can't say for certain if I really like it or not. However, its ideas are apparently done well enough that some people liked it, so you should probably give it a go later.
The rest of those games are largely forgettable, with the possible exception of Sorcery which I don't know anything about.
DNF is second place? Man, you guys are assholes.
Well yeah, but finishing DNF was far more cathartic than I ever expected it to be. It's the video game equivalent of someone shooting you only to have the bullet bounce off something in your shirt pocket.
I would put AC2 as my favorite of the games on that list, although Driver SF has its moments. Haven't played most of them, alas.
This would be my first two, as well.
Maybe God of War, but I'm not sure how it holds up. That part in Hades will prevent me from playing that game to completion ever again.
