Too many to list. Reviews are too often very generous.
So I'm going to limit myself to games with shitty gameplay mechanics that were often praised by forum members here as well as achieving wider acclaim.
Oblivion sucks as a action RPG, but it's doesn't work as a good roll-playing game either with no real strategy in the character building parts either. Just a horribly unbalanced game that rewards and encourages abusing the broken system (under-leveling). Extreme level-scaling and everything else being terrible, except for scenery being pretty for an old game, makes for a complete turd or a walking simulator.
For an open world CRPG play Fallout NV instead, or maybe even Skyrim, which is somewhat dumbed down again, but still manages to be better than it's predecessor. If decent combat mechanics are also a must, you're pretty much stuck with Amalur or Dragon's Dogma, unfortunately.
KOTOR doesn't work as a RTWP game (unlike BG2), because the interface is a mess and the player doesn't have direct RTS control over his companions, but it also doesn't work to control only the main PC, because the companion AI is just terrible. The overall result is a very clunky and unrewarding experience.
It's not hard to recommend something similar yet better here, since KOTOR is the worst Bioware game in this regard, along with the singleplayer part of NWN. As a sci-fi action-RPG with sappy dialogue choices, Mass Effect is good for what it is.
Galciv2 is a 4X game with all the tactical combat stripped out, resulting in a game that's mostly about managing a space empire's economy. Unfortunately the economy makes little sense (the slider problem), makes for a lot of boring busy work to play optimally and there's no game balance to be found (economic traits + population growth bonuses and speed trump everything else and the initial colony rush is everything).
A completely broken strategic AI ruin the rest of the experience, but exploiting AI stupidity is at the same time the only reason the player can compete with the cheating AI at the higher difficulty settings. This is true for most strategy games, but it's funny how it's doubly true for the AI advertised as the greatest.
Play Master of Orion 2 or Armada 2526 instead. Or just play Civilization, or just about any 4X out there really.
The Walking Dead The gameplay consists of quick time events and the occasional immobile prize shooting. The choose-your-own-adventure-book dialogue system is mostly fake and even the final outcome is fixed. The only thing going for it is that the story is okay, if a bit sentimental.
For a CYOAB, play Alpha Protocol instead, for all it's many flaws, it is the king in that area and at least it has actual gameplay.
Hell, the average Bioware title has more actual choices with consequences than TWD.
If what we want is a zombie-themed game, then just about everything out there plays better than TWD. Play L4D or something.
