OK... I've taken a step to handle this situation.
I realize that there's a lot of stuff in the 2600's extensive library that I've never really been that interested in, but some of it has come my way in big lots I've bought on eBay.
As a kid, I was really only aware of or interested in games by these companies: Atari, Activision, Imagic, M Network, Parker Brothers, and Coleco. I had a few games from other companies... Apollo, Data Age, US Games... but generally didn't care much for those games or about any of the others those companies made.
So as I've gotten into collecting, I'm really only interested in games by those same companies I cared about as a kid (with a few exceptions).
I've added a new classification to my database... "will consider trade." I went through and all of the games that have entered my collection by chance, and in which I have little interest, are now marked accordingly. I've stuck prices on them too, but they are deliberately high (based on rarity), since I mainly want to use these games (most of which are 3's or 4's) as trade bait.
OK... if you're still with me, then you may actually care a smidge about all of this, so in that case, perhaps we can arrange a trade. Here's the page with the pertinent info:

Please note: I am in the middle of a big move right now so I probably won't be able to deal with this stuff until January. But I'd be happy to commit to trades now as long as you don't mind waiting a couple weeks to get the goods.
