It has been mentioned before. And even if it was chosen as a high priority feature. It would be a lot of work and require a different skill set then what we have.
Even if we were animating X's and O's, we still have the bigger issue...
How do you move ("animate") the players around the court to actually look like a basketball game? The game play-by-play says "Player A takes a jump shot from X location", so what locations would the other players be on the court?
Also Hattrick has not 3d animation, and he has very important number of users and I think HtDevs.
BBDevs now concentring about improve mechanics of game-simulation and other aspect of game and app of course.
The app is very important and beta version is very lovable. I approciate their efforts to improve this game.
