Ahhh...very glad you gave us the ability to view all players in the organization from the roster screen. Man....I missed that from the pre-200x days.
I of course like new features...but I put more stock in how do I feel when I'm playing the game. In the past, there has always been that feeling of cool I like this new feature but the game fights me in terms of getting things done when I play it, something that I never felt in version 3 thru 6.5.
OOTP 9 has those "sweet...I love that new feature" and it also has the smooth "feeling" where I don't feel like I have to fight the game to manage my organization (at least so far).
So far the only things I've come across that are negative are fairly minor.
In the Webcast screen -
Any player green player rating is very difficult to read.
On my laptop at 1280 X 800, the team info stats get cut off by the bottom edge of the window (again in the Webcase screen).
That's really the only things I've come across that were remotely negative so far.
