Executive functionning seems really relevant for everything “personnal change” related. It is not only work, but discipline, impulse control, emotion control, self awareness, planification, etc.
Boosting executive functions would mean a lot for everybody who seeks growth and change in their lives.
How many times did you lack the discipline to do something you have to do? Follow your diet, go out socialising, ask a girl out, sit down and work, NOT eating an entire bag of cheetos, NOT sitting down in front of porn, going to the gym, meditate… Basically everything that is not easy and require willpower.
BLU and Commander partly influence Executive functionning, but an Ultima title solely dedicated to it? Sounds amazing to me!
