I bought Fallout 3 CE for 360 back in November, and decided to go very conservative on game spending after that.
I used to buy 2-3 games a month, but only play most of them for 5 minutes and keep them for later. I accumulated huge number of games over the years, so now, with crisis and all, I can use my back catalog 🙂
I will buy Killzone 2 in February, since it's the sole reason I bought PS3 back in 2007...
