Probably really only Xenoblade Chronicles since it's so rare and expensive now and the MP trilogy since they're such amazing games.
Honestly though, I skipped most of the 5th, 6th and 7th gens and am catching up now and I kind of wish I'd bought a LOT of games back when they were popular and new. Probably would have made it more exciting.
It'll be awhile before I figure out how to do one of these. :P
