Here's my dose of bile:
Crusader Kings 2: Probably the best game I played this year but still has bad AI and some ridiculously gamey elements which are very easy for the player to exploit making it fairly easy to conquer half of Europe starting with a small county if you know the mechanics.
And while they have improved it with patches, I hate how easy assassinations were in the beginning, making it seem like some cheesy medieval version of the Sopranos or something..
Guild Wars 2: We were promised "dynamic events" and a revolution in MMO design. We got escort quest "events" that reset every 5 minutes so you have even less feeling of having accomplished something than in a WoW quest. Also why did they make it so you are inundated with skills for the 1st 10 levels and then it takes you 10-20 levels to gain another skill which makes leveling up boring and pointless for the most part? GW2 still is a decent game but was over-hyped as hell.
X-Com. I liked this for the first couple of hours but then realized that all the missions are basically the same thing over and over. Also, why do all of your "international" soldiers speak with cheesy American accents? I mean I wouldn't expect them to hire a voice actor from every country but you could have at least got a German, Brit, Arab, Chinese guy and African for example to give a little variety.
Dishonoured: I didn't get very far in this one so maybe shouldn't judge it at all but it bored me. Beautiful set pieces but just the same old "go in and kill a bunch of dudes" game play or if you want you can sneak past the duded because we're super innovative. I don't get the praise this got at all.
Out of the Park Baseball 13: Have been playing this series for 12 years now and always sink a good few hours into the latest installment, but to be honest, the innovations every year are quite small. I will still buy number 14 next year though. :)
Overall, a pretty meh year for new games I'd say :(
