Tales of Symphonia was better last gen. Hopefully, that will change will change (for the Tales of franchise) with Graces and Vesperia (I am waiting for the PS3 version).
Mario Galaxy was terrific, though I think 64 was better.
Fire Emblem is better this gen.
Resident Evil is worse. RE4 was fun, but I enjoyed more the GC remake of 1. I am not interested in RE5.
House of the Dead: Overkill was a blast.
Zelda... Well, I personaly think that Twilight Princess was the first NPC out there (with RE4), so I guess I should wait till the new iteration is released. Though if it is true that it will be M+ compatible and harder it will be definitely better.
