Enh... In an action-y game, there's a strong argument that mastering difficult controls can be half the fun. In a menu-based management game, I want the controls to be as streamlined and intuitive as possible, always. It should be my knowledge and planning ability being tested, not my muscle memory.

Or to put it another way, if I'm pretending to manage a fortress, losing because I was too focused on expansion and didn't stock enough food and ammunition to survive a siege can be fun. Losing because I was fully prepared but forgot how to tell my minions to raise the drawbridge and man the walls is just frustrating.
