FFX-2 and FFXII. Never before had I met games in which I desired more NOT to finish them, but I wound up doing so, simply because I paid for them, so it might as well be worth my money.

I made it back in FFXII. I'm still waiting for FFX-2.

Other than that, there's the games I do enjoy, but can't ever be arsed to complete them, due to restrictions on my time.
