Mine is Lightning Returns: FF13. I think I've come across one person who genuinely liked it on the site. I usually don't like to run against the clock but I thought it gave the game a momentum and a pace. The story was so awfully written and told, I eventually began to enjoy the sheer absurdity of it. The majority of the Garbs, the costumes/dress-spheres of the game, were actually really cool and badass looking. There were some memorable tunes. And lastly, the combat is one of my favorites in all of gaming. The blend of active time paradigm with the dress-sphere system is a true achievement. So good, love it.
The game for sure has a ton of problems. I wish the story was actually good, not ironically. The performance of the game is quite bad (at least on PS3) and while the art direction, particularly the architecture is striking, the game can look quite drab.
A contender for me is BioShock 2. It's another game I hold in high regard because of its combat. Setting up traps with the full array of your arsenal and watching splicers trigger them to their demise is a thing of beauty.
