FFVIII. I would say the whole smurfing game, but that would be a little too judgmental. I think the whole "Oh, the GFs made us lose all our memories and we've actually known each other since we were kids" thing is possibly the worst plot twist I've ever seen. I seriously imagine a group of Squaresoft writers sitting in a room, halfway done with their game, and coming to the conclusion that their game wasn't going anywhere, so they had to throw some in there to tie it all together. Bad, bad, bad, bad.
