Burnout Legends near the top.^ That's what I've been playing lately.
On topic: I used to get excited about finding older PC Engine CD's on eBay, and I would pay a lot for them too. But even though I would be happy whilst waiting for their arrival in the mail, I would only play them for a wee bit before putting them on the shelf. I considered myself to be a collector, but quite honestly, the surplus of unplayed games just made me feel incredibly empty inside, and it was actually nice to sell them recently to people who were overjoyed to purchase them.
In a way that has transferred over to emulation to some degree in that I now have trouble focusing on a single game. As for the money aspect, I suppose I didn't feel great about shelling out a hundred dollars for an older game just because it was rare, so I guess I'm not really a true collector. But either way, whether a game is bought or downloaded, it should be appreciated, and I have yet to fully relearn that simple truth.
