I wish for...consistent and standard ESC key behavior.
I wished for the same thing in GC2 and WOM.
It's partially happening in FE, but not across the board.
The ESC key should close open windows.
If no windows are open, it should pop up the game menu.
There are some windows in FE that don't require input that pop up and you can't ESC out of them OR if you hit ESC the game menu appears on top of the unclosable window.
