Yeah, I'm not someone who generally collects everything. I have a big library of games that I play and have played, a small stash of nicer stuff and CEs that makes up a pretty pitiful "collection", and the rest of it is stuff I buy and sell on eBay. That's why you see a lot of older games for really cheap. There's little use in "building" them because I'm not a collector; it's more profitable to sell them as-is (sometimes it's even more profitable to sell each disc in 3-4 disc games separately!).
Anyways, as far as CE/nice stuff I have there's the Cataclysm box ($50 on that), PC MW2 LCE (I think I have $30 on that, it's near mint), FF VII (black label, but in rough shape, $35), Bust-A-Groove 2 (disc only, but it's rare, $40), a mint copy of Wind Waker ($43), etc. I know it's a bit hard to wade through the loose stuff on my topic, lol.
If you're not interested in any of that, no big. Just putting it out there.
