I had the Dr Kawashima's Brain Training for the DS last year, and sold it since nobody had played it for about 3 months. My whole family (parents and younger brother) had profiles, so a few months later when my Mom tried to play it at Christmas just gone, she was pissed off when I told her I'd sold it. It was just gathering dust anyway, and it was extra money towards Gears of War... Anyway, she got me Big Brain Academy (and some weird but fun game called Professor Leyton, a puzzle game) at Christmas then proceeded to steal my DS until Easter while I'm at university so she could play them. There's gratitude for you...
