I just finished Call of Duty 4 on Veteran over the weekend (xbox 360). I have another 120 points remaining but some of them are darn difficult for me. I only got the game the on last Monday. I could not stop playing. It was that fun. Never before I had finished another game on the hardest difficulty within a week.
I play mostly FPS games. I could never get the hang of other genres other than puzzles and a bit of racing.
My library of games is like almost all Call of Duty games starting with Call of duty games on original xbox and CoD2 on PC and then xbox 360, Gears of War, Halo2 and 3, Resistance etc. I no longer play on PC except solitaire. I lost touch with keyboard and mouse play. Doom 2!
What game are you playing?
