I picked up a sealed copy of Pokemon Gold at a closing down sale in January (what makes it even better is when I got home I realised I hadn't even been charged for it :) ).
Of the top of my head I have DKC 1 & 3, Marvel Vs Capcom 2, Paper Mario: The Thousand-Year Door, The Legend of Zelda: Ocarina of Time / Master Quest, Baten Kaitos: Eternal Wings and the Lost Ocean
