I wish we'd get another Left 4 Dead, and while I don't feel like TF2 really needs a new game, it could probably do with a fresh coat of paint (like PBR materials).
DoD was the first FPS I ever played that had mouse aiming. That sounded dumb to me so I just camped in crowded areas with a machine gun and waited for people to run into my crosshairs.
I cannot aim and also have a crap mouse (don't really want to spend money on anything gaming related) so I alternate between MG and nade runs. Small maps are great for nading all night long.
Goddamn, for real. Left 4 Dead 2 is one of my favorite games of all time, maybe even my favorite. Everything that's there adds to the experience and is finely tuned and crafted. It just plays so well that it's the only game that Ive played for over 200 hours and still go back to that has no meta progression whatsoever, aside from achievements I don't even chase.
I mean, half-life recently got a new game. It wasn't Half-Life 3/HL2:EP3, but it was more recent than L4D and TF2; which tend to be forgotten about until people start complaining.
