I've been itching for a new MMO since I quit WoW a few months ago. Can't wait for SWTOR.

Bought Stalker: CoP for a buddy. He's always playing Shadow of Chernobyl and hasn't picked up any of the sequels, so I thought I'd grab it for him. He was pretty excited :D

Thinking of picking up the Dead Space pack...

Get the STALKER pack for sure. Excellent game. The atmosphere is especially good.

I played both Morriwind and Oblivion on the Xbox and 360 respectively when they launched and thought they were great. When I got my self a gaming rig I bought them both on steam and modded them. The mods make themeven better.

I picked up Fallout New Vegas to hold me over until Skyrim. Its done the job well.

Star Wars Knights of the Old Republic is by far my favorite RPG of all time. If you haven't played that I strongly suggest it, especially if you enjoyed Mass Effect.

Star Wars: Knights of the Old Republic

If you'd look around on the internet you could be playing it right now ;)

As far as series go: Fallout, The Elder Scrolls, KoTOR, Mass Effect, and Diablo.

Metro 2033, Fallout 3, or Fallout New Vegas.
