fronzelneekburm: Probably Bioshock. Sure, there have been far greater stinkers than Bioshock, but with Bioshock I found the discrepancy between the absurd amounts of praise the game received and the actual game to be the most jarring.
I have to agree. This game was hyped all to hell, but it was boring as fuck. It looked nice, but the game just felt so tacky and repetitive. It was almost like they decided to slap "adult" visuals on some childish Mario type game.
The Witcher series. I hated the first one. I hated the second one. I wanted to play the third on... just to see the story all the way through, but I lost my saves from the first two because it took so damn long for the last one to come out (why the fuck do I need to keep my saves anyway? For years? Who the fuck thought this shit up? And yeah, I know it has those options in the beginning, but that's not the same as having your saves. You don't get all the little character interactions you get when you have your previous saves.)... and I hated the game play, and I hated the story. It was all just boring as fuck.
The original main story was interesting, but most of the game was "old granny lost her boy, go find him" or "there's that evil spitty plant there we could light on fire with burning arrows, but we gonna spend our money on a Witcher instead" or "go whack these stupid fish men that keep popping up cause we keep drowning folks in our river for some bizarre reason" or "whack that mute-y the king made by fucking his sister" or "there's that bizarre nuisance thang thar, go whack it wit yo sword"... I mean... The whole series just feels uninspired.
And then they didn't put it on Linux.
But the most disappointing to me is the Metro series. It's only available on steam. And I will not touch valve with a 10 foot pole. So I cannot play it. And I really liked the first one.
