i think i'm at the point where i have so many games on my HD that, no matter what goes on sale, i'm not really going to care, as i've bought at least 95% of the games i have any interest in. Like maybe .5% of the total stuff that could possibly go on sale is stuff i would consider (not counting GODs, i like converting to digital but those go on sale so rarely i wouldn't even count them) buying, even at a discount. i think i can count everything on one hand. ME2 DLC (wasn't into ME last year), crazy taxi, hell yeah!. people complain about MS sales all the time but in just one year since i rebought an xbox i've snagged at least 70 really good games for really cheap (after counting discounted MSP to stack with sales of course) and its hard for me to even think of other games that are worth my time.
So more than anything i guess i would prefer to see GODs start getting slashed. they did a good job of that a few months ago then randomly just stopped discounting them, turbo lame.
