I do, though I always tell myself I'll get around to them. While I always buy stuff I would/want to play, the main problem is my backlog is just too big, so I'm perpetually 'behind' on stuff. Online games like Destiny and FFXIV tend to add to that backlog, since I'm not actively progressing through the stack lol
Still, I keep buying, and I don't really sell anything unless it's something I just flat out didn't like, or wound up with multiple copies of.
