Unlimited Saga - For reasons most who have played it will understand, just unplayable and not enjoyable in the least.

Holy Magic Century/Quest 64 - Just a game that tried to be challenging but how it was done was ridiculous and as the only RPG on the system for ages made it worse.

Vagrant Story - I really want to like this game and love the setting but the endless changing weapons, weak battle system and general gameplay never sucked me into it.
