I didn't like 10 that much either never beat it on the PS2 but might beat the remastered version on the PS3 eventually.  Never played 11.  Didn't like 12 that much either since it played too much like a MMORPG and 13 isn't that great either.  Skipped 14 like 11.  My expectations for 15 are pretty low.

Deus Ex Human Revolution

Also agree with those that picked GTA IV and Skyrim.

Final Fantasy VI and Oblivion.

Both of which I full on disliked, which is odd, because their sequels are some of my favourite games of all time.

MGS4, Gears of War, Smash Bros games....Oh and for all the people who love team ICO....ICO was a horribly overrated game.

Bioshock. I couldn't even finish level 2 of how bad it was for me. Worst $5 I spent on PSN.

So many...

- Halo 1, 2 and 3. Rigid Gameplay, very, very dated graphically, meh narration. Only the masterchief, Cortana and vehicule did save it.

- GTA IV : A gta where it's a pain to drive cars ? Niko Bellic must be the dumbest and ugliest character I have ever played.

- Bioshock. No much to say, just a bad game IMO. Only saved because of this story but I rarely play a game only for its story.

- All the Assassin's creed.

- All Uncharted except the 2 one.

Almost all Valve titles, Smash 3ds (honestly, I love the series and the genre overall, but that not that one), Bioshock, Skyrim (too many glitches and retarded IA), all Cod games (they're fun in 4-players split screen but that's it), Rayman Origins.... what about the Wii ? I know it's a console and not a game, but I think the Wiimote (and the bad use of it too) ruined most of those awesome games released on that console, I really hate that motion stuff and the analog on the "knuck-something" felt really cheep, and I'll never understand why it was made around an octagon instead of a circle, the point of the analogs is that you can move in a lot numbers of directions.... seriously, Wii is actually the best console I have when I use other controllers lol.

Destiny is, by far, the most overhyped game I've ever seen.  

Elders Scroll IV: Oblivion. I bought the game because of the great reviews and because it was a Rpg. Skyrim, IMO, was a better game.

I guess Majora's Mask. Maybe I wouldn't say I "dislike" it, but I like it a lot less than I do all the other Zelda games I've played.
