I know I'm beating a dead horse here, given the number of times I've said that Luigi's Mansion is shit and in a better multiverse it wouldn't have existed, but Luigi's Mansion. I haven't played the sequel, and I don't plan to unless I find it for like $5 somewhere down the line (or my brother decides to get it for one reason or another to play on my 3DS, or something), but the original is probably my least favorite game that I've ever played all the way through. And I know a lot of people like it, fine, if that's your thing, I guess Nintendo deserves the money you'll give them, if only because they make so many better games. But in my opinion, Luigi's Mansion was a horrible game, completely undeserving of a sequel.
Also, within The Legend of Zelda, I feel like I've made this complaint before, but we really didn't need TWO fucking sequels to The Wind Waker. Spirit Tracks at least was good, haven't gotten around to Phantom Hourglass, but really. We didn't need to see any more of Toon Link. We didn't need to see any more of Toon Zelda. And even if we did, my opinion is that their first game certainly didn't indicate that we needed to see them again. I know The Legend of Zelda: The Wind Waker has a lot of fans, and, again, Nintendo deserves your money, those guys publish PokÃ©mon and the good Zelda games so they deserve ALL your money. But the game in question itself was far too monotonous, especially the last third of it which was just one big fetch quest on the endless sea. Not to mention how I feel to this day that Ganondorf had a point: Hyrule was a land rich in resources of all kinds, but to stop one man from conquering it, the gods flooded it and turned it into a fishless sea, drove some of its people to barren mountaintops and left the rest to drown, basically abandoning the people. Every complaint that antitheists have about the Abrahamic God is RIGHT THERE in the actions of Hyrule's deities. Ganondorf may have been bad, I played Ocarina of Time so I'm not going to deny that, but he only drove the people of one town out to another town with a few zombies, drove a princess into exile, froze a river, and had a few Gorons locked up for treason against the new ruler of Hyrule. Standard (if decidedly not righteous) conqueror routine. And he kidnapped a few girls while looking for the Princess while trying to get control again. Evil? Yes. Definitely. But I still say he's better for Hyrule than the legitimate gods: Ganondorf at least didn't kill what was almost certainly the majority of the population when he conquered them. At least, he's better as they're portrayed in WW. The developers did a much better job of making Ganondorf seem like the real villain and the gods seem benevolent if distant in TP (albeit at the cost of making Zant a mere underling, which is a common complaint against the game). When a game makes its protagonist seem like they're working for someone worse than the antagonist, it's supposed to be an artistic decision to make the world seem bleaker and less hopeful, not the result of fridge logic. And that's why they should have continued Twilight Princess instead of The Wind Waker: say what you will about TP being hijacked by Ganon, it at least makes its villains as evil as it tries to make them, and doesn't spend the fourth quarter fumbling on every play.
