I wasn't going to buy this year's edition, because I was very disappointed with some aspects of 2k12. And then I played the 2k13 demo and I'm instantly sold on this new version. They seem to have addressed all the things that bothered me, and the gameplay is miles better than any other 2K in all aspects.
Mainly, the movement of players, the fundamentals, now are amazing. Speed, weight, positioning, everything seems to be reworked a lot. The way player dribble, drive to the basket, even the screens.. it looks and feels very realistic and simple to perform. I just spent a full quarter moving around to see how everything worked. Pure class.
And the right stick controls are great, once you get used to it it's second nature.
So, I will definitely buy it at the end, because this has written GOTY everywhere. Presentation is great as well, much better than before, and things like stealing have been improved (you can "feel" you go for the ball). And the ball physics, the new bouncing passes, the way bodies collide in the air and the reactions of players. Just amazing stuff.
Seems that 2K are back to take the crown.
