Alpha Protocol is definitely up there. I've only finished it once, as an assault rifle soldier since it was recommended everywhere, so I have no idea how the game plays with a melee/stealth -character (poorly, from what I've heard). But I thought my game experience with the soldier was a good one, definitely above average. The choices you could make everywhere were really interesting.
That's all I can think of top of my head.
But when the tables are turned, I've got a few more titles in mind. I mean, if the question was "what games did you hate, that were universally acclaimed by critics".
First of all, Saints Row 3. SR2 was like the best thing ever with a partner, but the third one is just too much over the top. It's beyond ridiculous. The game is also significantly shorter than the previous Saints Row games, the map seems a little smaller and it's not fun to explore at all. The AI is constantly on your ass shooting at you, even when you think you didn't do anything. And the plot sucks (again, it's ridiculous). However, most critics seem to think this is a really good game, the best of the series. I disagree, and was severely disappointed seeing how SR2 was so much fun. 2/10
Then, Mirror's Edge. It looks pretty, but plays awful. I can't count how many times I hit the ground because I couldn't see ****. 1st person parkour just does not work for me, with Assassins Creed it's a lot easier (and more fun!) The objectives were always the same: run to point B from point A, while dodging conveniently places objects and gun-toting enemies: repetition. The contrast between light and dark was too great, and I was forced to lower brightness every time I was outdoors, and raise it again when I went indoors. 4/10
Super Meat Boy: I just can't seem to grasp, what is so fun about dying repeatedly in an over-elaborate death trap of a level. Granted, I've only played this one for about an hour, but I have no desire to go back to it (and also, I'm not really a platform-type of guy). Therefor, no grade.
Revenge of the Titans: Aggravating, that's all I can say. I know it's not a traditional tower defense, but I HATE how the aliens won't follow a pre-determined path. You can create turrets all you want, until at some point the aliens just say "screw it", and run over all your turrets, leaving you helpless watching the demolition. -5/10.
Team Fortress 2: How is this so popular?? To me, it looks like a regular MP shooter, plus the menu interface isn't the easiest one to navigate. Still for some reason, there are tons of players and the trading market is flooded with different TF2 items. WHO THE HELL PAYS 100-200 DOLLARS FOR A GODDAMN HAT?? The game is just...weird. Giraffe/10.
