I still play Gears 1 PC online sometimes. Fun stuff.
Plus I'm STILL playing through the campaign AGAIN for like the third time. Every time Lost Planet, Bioshock, Far Cry 2, HAWX or Mirror's Edge (the games I play with a wireless 360pad on my TV) piss me off I play Gears. lol, matter of fact, I've ditched Metro 2033 for Gears a couple times as well.
I sure hope Marcus Fenix comes back to the PC.
