Since this is my initial impressions...
1. The import function should grab ballpark models. I hadn't worried because it had the stadium name, and all of the factors correct, but when I started a game it was the default major league ballpark. Annoying rather than a game breaker.
2. I will need some time to get used to the new UI. Again, I wish that it grabbed the settings from 21 as it took a bit of time, and will take more, to get everything in its place so I can quickly get data that I'd become accustomed to.
3. Shadowing on the players in 3D mode is extreme. It is as if they are backlit from center field.
