Most of the games I bought for my Atari. The majority of them were garbage.
Pre-ordering LA Noire at full price. I was super excited for that game, I even bragged to people that it was going to be a "game changer" and I never do stuff like that.
When I sold my video store, I had the opportunity to take a bunch of old PS1 and PS2 games with me but I didn't. I really regret not grabbing some of my favorites when I had the chance.
