After watching various skill levels playing I can say the following
- Demo 3pt shooting is tuned very high. So that appears to be a difficulty setting/ slider tuning thing. If somebody has a good 3pt you can really get hot it was the same way in 2k12 demo. It is most likely like this on purpose
- There is better contact in the paint shot success and shot types are much better. I didn't see the awkward layups or awkward contact shots.
- Passing is faster and the passing seems to be a little less predetermined meaning you can step in and alter the outcome or the pass may go long. There is less herky jerky passing as you seem to be able to hit players in stride. I am happy to see this.
- The isomotion looks superb it looks like it will be easy to use. It also looks like they balanced the dribbling out by if you try to do too much you will lose the drbibble or do isomotion with the wrong player.
- The dunk animations are nice improved less floaty, the verticals heights of the dunks happen at are realistic.
- Animations are improved
