On the terms of being different, I'll go with Sudeki on the original Xbox.
The game starts off fun, each battle playing out in either a first person shooter or a hack and slash, each in real time, the special moves were pretty cool, and the story was fairly well done. This is one of those RPG's that pulls you in, due to it's slight inventiveness.
Then came the second half. If you're looking about at this point, you should already have every character's ultimate weapon, making the chore of searching around after this point nearly null and void. The game began to spin schizophrenically in between simple and complete bullshit levels of difficulty, and the story began taking a nose dive toward the very end. They close off areas you've been before, so you couldn't complete certain quests, and if you didn't power up Tal, a melee fighter and one of the four main characters, the most, the final boss was near impossible because you fight him alone.
