I probably do 10-12 hours a week. Mostly Left 4 Dead at lunchtimes at work, and in the evenings every other day. A bit of ETQW and Q3 here and there. Does Brink count? :)
average week: 0-1 hours. when i get something i can sink my teeth into it jumps to 10-12 hours. last games for me in that vein were fallout 3, mass effect, lost odyssey, and bioshock.
Have to agree with chrizz1. Love playing games, but I am always thinking about what could I've done for my portfolio to get into gaming industry. Mostly TF2 and about 10-12 hours a week. Hope to play some more or just relax when I finally land a job. :) Pitty I am in Europe so its hard to get and play with some CGTalk…
