This year's MUT has had the worst user interface I've seen in any major title ever, and has been awful by even recent EA standards.
The game freezes if I try to build a set with an item I just acquired.
The game hangs randomly at menus of every sort.
The game at times allows the user to interact with multiple layers of menus simultaneously (for example, I'm trying to list an item on Auction House immediately after a purchase, and somehow I'm also trying to purchase an item on the Auction House).
I can understand why the AI can be flawed when it comes to complex rules that apply with certain kinds of coverages, like zone coverages and man assignment switches against bunch formations. I can't understand why menus, the most easily flow-chartable aspect of any program, are this dysfunctional in MUT.
