I sold my entire collection in 2009 I think. I needed cash for something.
All my Atari Jag/CD, TG16, and 3DO stuff was sold off. I proceeded to buy it back last year...which has been fun, but also a big mistake at the same time. Prices sure jumped since I sold my collection. Still have not been able to replace a few items. I had Rayman CIB for Jaguar, and New Adventure Island for TG16 CIB as well. Those really jumped since I bought and sold them. Don't think I will end up replacing those....
But still, if you don't play those NES games and/or they suck, get rid of them. I use the "play/test with a buddy" method. Every other week I get together with a friend and we try about 10 games out from our collections that we have not played. If we don't like it in the first 30 minutes, its typically a sell/trade. If we like it enough, we will play it again in a few weeks. If it holds up, its a keeper. If not, its a sell/trade. We just played Double Dragon II tonight. It's a sell...
