Everyone has games that they really liked, and a lot of those games end up having sequels. Sometimes those sequels really don't do the series justice. A recent-ish sequel that i hated was Force Unleashed 2. It felt so linear, repetative and in many respects heartless. There was no real soul or atmosphere to it.
This. TFU was a solid game, really fun, but it had a few issues that kept it from being really great. I really hoped TFU2 would fix those issues and help the series live up to its potential, but it kept all the issues from the first game, eliminated the great story, was half the length, and was just overall a disappointment.
And the animations really got me too. If you threw the lightsabres, regardless of where you aimed, it would cut off the enemies head, sometimes multiple enemies. It wouldn't of killed them to add a bit of variety to it.
Do Pokémon Diamond and Pearl count? When they first came out, and I was just a little nooblet, I thought they were amazing. After a few years, though, I couldn't stand them. :/ They felt slow, clunky, and kinda boring. I especially hated the story. I haven't played Platinum, but I heard that it fixed a lot of the issues from D/P. I know for a fact that HG/SS and B/W did. Another sequel that let me down was Golden Sun: Dark Dawn. Don't get me wrong-- I like the game. It's one of the better DS games out there, which is saying something, considering it copies the gameplay of a game that's about ten-years-old now. The only problem is that Camelot made the game way too easy. The original GS games weren't exactly hard, but they weren't as insulting as Dark Dawn is. Another thing I hated was the story: while there's good plot development, the whole game feels like a gigantic side mission. It even reminds you of that after the credits. I hope that if a sequel is made (which I'm certain will happen), Camelot at least makes it as challenging as the original Fame Boy Advance games.
I'd say they count since the pokemon games run a very, very loose canon between them. I wouldn't say it's a terrible game but a sequel i have actually come to hate is Metal Gear Solid 2. A lot of people hate MGS2 for the stupid reason that you play as Raiden, but that is honestly far from the problem. MGS2 is a really, really bland and repetative game. The Big Shell enviroment is awful, the pace feels irratic and tacked together, the scenes that are supposed to be emotional aren't because they focus on characters that have only been introuduced in the prior hour max (Emma's death, Stillman's death etc) and with the exclusion of the Harrier bossfight (which is just an intentional reskin of the MGS HIND-D boss) are terribleame redee and uninventive. The game redeems itself in the Arsenal Gear portion but it's too little too late. And don't even get me started on the overly pretentious and confusing plot.
Recently, Dark Souls. It's EVEN HARDER than Demon's Souls and doesn't quite have the polished level design, which I attribute to the change to an open-world format. Merchants are more difficult to locate, you're capped to five heals per life, and enemy firebombs are way overpowered in the early game. It crossed the line from difficult to cheap.
The Legend of Zelda: Spirit Tracks. Probably the worst Zelda game there is. If you look up boring or soulless in the dictionary it will show this game.
I haaaaaated Spirit Tracks. I thought Phantom Hourglass was a really good game with some flaws, but Spirit Tracks was the epitome of generic and uninspired. And the train was an absolute chore - especially since all the enemy spawns were predetermined and the backgrounds were so bland.
Metroid Prime 2 Echoes The light vs. dark idea has been done sooooo many times so no points for originality in terms of story. Visually the light world was beautiful while the dark world was bland. Just because it's called the "dark" world doesn't mean there shouldn't be any colours other than black, gray, and purple. The light world was very colourful; it wasn't just white. And it was unfairly difficult. The save stations were few and far between and the bosses were brutal, especially the Emporer Ing. Banjo-Kazooie: Nuts & Bolts Visually it's great but the gameplay is too different and frankly mediocre. I don't understand why Rare doesn't produce another platformer-based Banjo-Kazooie game. Super Mario Bros.: The Lost Levels This game is brutal. I don't think I'll finish it... or return to it actually. Animal Crossing: City Folk It's essentially just a port of AC: Wild World but with some minor new features. Very disappointing.
Bioshock 2 was so depressingly bad. :( I know the big thing for it was the online VS mode (which I have never touched). But I'd heard it was only so-so compared to the original, so it's not even like I went into it expecting greatness. If anything, after I played it, I regretted spending almost $15 whole dollars on it. It wasn't creepy at all, you were way too overpowered compared to the original, guarding the Little Sisters was such a chore, and by the end of the game I was just praying for it to end. In essence, it pretty much guaranteed I will never buy Bioshock Infinite (is that what it's called?) since if they couldn't even get the feel of a direct sequel set in Rapture right, they sure as hell aren't gonna rope me in with a bright and sunny game. edit: Oh yeah, and Tales of Symphonia 2 was pretty awful as well.
