I think I bought some stuff from GoG ages ago, but I totally forgot about its existence until now. It's a brilliant site, I don't pirate/emulate games so I get really excited whenever I can find retro games for sale :D

I never had the Saturn, so I don't think I've played any of those games. I miss some of the games for the Genesis, though. (I think there was a Sonic game which had a Knuckles expansion pack, and you had to plug one cart into the top of the other cart or something. Crazy old technology is great.)
