Battle Arena Toshinden, Blaster Master, and The Lost World were all games that I remember wanting after seeing them at Toys R Us back when they still had the walls with the plastic flaps that had the game cover and back on them. I've been on a PS1 kick for a couple weeks and they were cheap so I got them.
I played Resident Evil 3 on Dreamcast years ago and wanted to pick it up again so I got that.
Parasite Eve & the collector's CD were kind of an accidental pick-ups. I was on eBay looking for Parasite Eve 2 and saw an auction for a black label copy of the first game (which I already have). There was 20 minutes left on the auction and I think the bid was only two dollars. The auction said the collector's disc was missing and the game discs had light scratches that didn't affect game play. I bid, thinking I probably wouldn't win it for what I bid. It's one of my favorite games for PS1 and I always recommend it to my friends so I figured having one to loan out would be a good idea. I ended up winning it for ~$7 shipped. Then my OCD got the best of me thinking about the collector's CD being missing and I went ahead and did the cheapest BIN on eBay. So both together came up to $11 for a complete copy which sounded good to me. When the game showed up, it was complete WITH the collector's CD and the discs were flawless. I don't know what scratches the seller saw, but there are none on the discs that were sent to me. So now I have an extra 1998 collector's CD vol. 1. Going to have to put it back up on eBay to get rid of it.
As for Parasite Eve 2, like I said above, I had been looking to get this for a while. My local mom & pop game store sells it used for $29.99 + tax. I bid on probably a dozen eBay auctions before winning it for ~$26 shipped. Probably paid too much, but I've really been wanting my own copy for a long time.
