Ugh!
Crap, crap, and more crap. I still can't figure out how Splinter Cell ended up becoming such a hit series. It's slow, plodding trial and error gameplay. Wow! You get to replay the same segment over and over 20 times in a row until you play the game EXACTLY the way the developers intended the level to be beaten. Game of the Year!
Then there's Prince of Persia. Now, I don't hate this game like Paladin does, but it was by no means GOTY. Not even frigging close. And it was buggy as hell, but none of the reviewers happened to notice that. I suspect Warrior Within must've been nigh unplayable with its bugs, since the reviewers actually mentioned them in their reviews, and actually gave this sequel something other than a perfect score.
Beyond Good & Evil was the only Ubi game that actually warranted a sequel, and it looks like there's no chance of that happening. Looking at the way Ubisoft is becoming, I'm not sure I would want them to make a sequel to it now. They'd probably pull a Warrior Within. Just imagine, Jade's career in photo-journalism isn't working out, so she has to become a stripper. It would sell 5 million copies.
