I'm calling "special circumstances". gog.com, direct2drive.com, and Steam are running sales that, frankly are bordering on complete madness. Direct2Drive has compounded this by giving me a $5 credit for free. I'm not sure how, exactly, they're making any money off of some of this stuff, but I'd be a fool to pass it up. I'll post more once I've made my final decisions, but I'm definitely going to take advantage. The games backlog will likely be growing by several titles.
