Half Life 2: Talk about overrated. This is one of the most boring games I've ever played, and that's coming from someone who has played Wii Music. PC elitists proudly tout this as the holiest of holy PC games, all hail gaben, messiah of video games. If that's the case, I'm glad I'm a console peasant.
Super Mario Galaxy: Both of them. Okay, I don't hate them - they're good games! Objectively it's hard to say they're not. But the amount of sheer blind praise these two games get (mostly the second one) annoys me to the point I never want to play them again. They're both so linear, yet they get praised for their "openness". Well guess what? Just because Mario gets shot through space from one tiny planet to another doesn't make the game open. You're still following a very intended path. It's called an illusion. What makes this worse is Sunshine and 64 before it. They both had large open hubs connecting all of the game worlds together allowing you to largely do things in the order you want. But then the Galaxy games decide to restrict that largely. There's still a hub, but it's very small and there's no reason to explore it. You still have the ability to mostly choose what order you want to do things, but that's restricted some too. Fun right?! And yet people clamor for Super Mario Galaxy 3 instead of a better - original - Mario game. The music is fantastic, though.
Xenoblade Chronicles: I love RPGs but I hate MMOs. Actually, I'm finding lately that I don't like many modern RPGs, but that's another story. Xenoblade plays essentially like an offline MMO. Sorta. I really just can't get into it. Also the music is probably the most overrated part about the game. Yeah, deal with it.
Final Fantasy X: Speaking of modern RPGs... I absolutely loathe this game. Annoying characters, stupid plot full of large holes, subpar music, and the Sphere Grid is SquareEnix's beginning of introducing the illusion of freedom in "customizing" your characters in the Final Fantasy series. But hey, at least the battle system is good. So let's never do that again except in the spinoff!
Final Fantasy XIII: Not universally loved, but strangely this game is getting more support these days than it used to. And it really shouldn't. It deserves all the hate it gets and then some. This has all the complaints I have from FFX except multiplied by 1,000. Every time Snow appears on screen and talks it just makes me want to jam a screwdriver through my ear to end the pain. This is quite literally the worst game I've ever played. At least the graphics are nice.
Pokemon: I kind of get it, but c'mon. Everyone goes on about how every Call of Duty game is just a rehash (which they are, and Call of Duty sucks too) but if you say that about Pokemon then it's suddenly HOW DARE YOU SLANDER THE NAME OF OUR BELOVED! In fact, it's more of a rehash than Call of Duty and it's worse because they release 2 games at once and people actually buy both of them. But okay, that's your choice if you do that. I'll be the first to admit I have bought and enjoyed blatant cash grabs and rehashes. That doesn't change the fact that the Pokemon series is dull and not fun in any way at all, though.
And then these games/series, because I'm tired of explaining why I hate all of this: LittleBigPlanet, Grand Theft Auto, LEAGUE OF LEGENDS, Mass Effect, Halo, Monster Hunter.
Oh yeah, and Sonic the Hedgehog 2! It isn't a bad game, and really most of the classic Sonic games aren't, but it also isn't very good. I suppose I just have a problem with games that encourage you to go as fast as possible but also to expect you to also collect rings, power ups, and to not run into walls every 3 seconds. Really it's just a mediocre game.
