Ehh, my brother would buy games for the stupidest reasons too... he buys any game with a peripheral needed, plays them once and puts them on the shelf (Wii Fit, Guitar Hero, Rock Band, DK Jungle Beat), he'll buy games "just to see how bad they are" (i.e. the BK games, obscure NES games like "To The Earth", wanted to buy Virtual Hydlide on Saturn), he bought a Spanish version of DuckTales NES just b/c it had a different cover...
If these people like Lost Odyssey, recommend them Tales of Vesperia or Blue Dragon.
