Haven't had a lot of time with v21 yet, but what I've seen is impressive.
Love being able to drag stat columns and group as I please.
Same with modifying the stat view on the player card, great stuff!
All the skins look great, dark is my preference but classic may get some time too.
Screens all look clean and polished. Stadiums have seen some love, and the camera options we now have really add to the experience.
Only disappointment is "scoring updates" has not been returned to the "out of town scoreboard" in modern 3d. I'll just keep asking, maybe one day?
Stellar work from Markus, Matt, all of OOTP developments and of course the beta testers.
Well done everybody!
