In case some of you are unaware, GMG is doing a massive sale right now for 50 titles that "you must play before you die." So far its been pretty impressive. Yesterday I picked up HL2: ep 2 for a buck and change and Portal 1 for $2.49. I didn't have either of those titles on PC. Today, I picked up Tomb Raider and wow. It is seriously one of the most beautiful games I've seen. I played it on console, but it's not even a comparison with everything up on PC.
Every few days the countdown adds new games. Keep a eye out for a title you've been waiting for!
