There is one mod called the Graphical Enhancement mod (Plus the HDR mod) which makes the game beautiful! You have to stuff around with the gamma and brightness options but if you get it right the game's graphics ptich forward several years. Worth looking at and can be combined with any mod.

I forgot one game which I can easily put at the top of a Most Wanted list; Operation Flashpoint Dragon Rising. I never had a good go with the original but I really liked ArmA, so if they make it better (Which isn't that hard when you consider it) it should go great. Release is off by several month's, possibly next year; but with the open world environment they're promising no wonder its taking so long.
