I do this every year, don't plan on breaking the tradition. Got to play only few games released this year, I was going mostly through my backlog, and did some catching up (Skyrim, most noticeably), thus I have only two games worth mentioning...

BioShock Infinite - my most anticipated game of 2013. Not was it just great, it managed to exceed my high expectations. There's a lot to love about Bioshock Infinite, though Elizabeth is by far its strongest point. She's charming, beautiful, though most importantly really helpful and intelligent, she can take care of her own which is quite rare in games with AI partners. Last but not least, the mind blowing end. Ken Levine is well known for these kinds of stunts, lets just say he more than delivered this time as well. Bioshock Infinite is all around a well made game, deserving of its praise, in a day and age of near indentical FPS's it's certainly a breath of fresh air.

Honorable Mention

Tomb Raider - a surprisingly well done reboot if I may say so. For the first time I was actually interested in Lara beyond her looks, she was well developed both via story and gameplay. The RPG elements were a nice touch. I do however mind lack of challenging puzzles.
