I finished outerworlds (freaking great game) so I've started adding to the backlog again...
Steambot Chronicles - I've wanted this for years. I've watched eBay auctions on and off and this game goes 80 plus easy. Someone had an ebay auction for one that was in the low 50's so with about 9 seconds left I bid 77 bucks. The game ran up to 91. BINs on decent copies get listed for 90 to 120. a day later I found an $80 BIN that looked immaculate. I bought it. it's freaking the nicest game I have in my ps2 collection now. I'm thinking someone has had the book and cover reproduced because its shape for its age is too good. I'll have to research but I don't care, the disc alone can go for 80.
Lesser value but still awesome games I also picked up are Mario Maker for the wii u (I've got a copy but this one was in great shape for just a few dollars) The Witch and the Hundred Knight - Revival Edition (I really have a soft spot for Atlus games), Suikoden 4, The Gran Stream Saga, Kingdom Hearts, Grandia 1, 2, xenosaga episode 2, metal gear solid 3, and dawn of mana.
I've really been looking for a reason to refurb an old ps2 and maybe nows my chance. I've kept tons of ide drives and bought network adapters and fat ps2s every time I've seen them out so maybe I can play around with hd loader and skip out on some load times. I faintly remember someone figuring out how to get 1080i out of one but if that doesn't work out I've got a hd link cable that'll do 720p.
