[quote name='suko_32']I forgot but did you end up ebaying/trading them?[/QUOTE]
Ebay for the most part.. I wanted to make money, not make trades

Some stuff I did trade off though, mostly the stuff that didn't sell on Ebay or was too much of a bitch to sell on there.
I just switched up my style and did auctions for some leftover systems / accessories and stuff, and it seemed to have worked out ok. I think I cut down about 80% of everything I owned.
My reasoning is that it will eventually show up on the VC / XBLA / PSN or a remake or a re-release.
It did save my ass from debt though, and it freed up a TON of extra space for me. I don't knock people who have big collections though, whatever floats your boat, because as Warner pointed out it's really good if you need extra money in a flash. I think I miss maybe 5 games out of the 800 or so I sold.
I *did* keep my systems (except the N64). I've got a Japanese white Saturn and a US Dreamcast... I kept those, plus the 4 in 1 for the Saturn to play US games and a few VMU's and my converter for the DC (to play imports).
It's a lot harder to find a working system on Ebay than it is to find a game... so one day if I want to get a few of these back it's as easy as just tracking down the game. The VC has me covered on N64 stuff (I only cared for Mario + Zelda, to be honest) so that got sold.
