Really good idea.
However, the "Your success depends on your intelligence rather than your wasted time" bothers me. That is how the average strategy game works.
It is to emphasis the contrast with an MMO, where most of the time, your progress is directly linked to the time spent playing, often doing the same repetitive tasks ad nauseam.
If that's it, they are mistaking "MMO" with "RPG", but I see the point. Maybe because to improve, you don't have to train by launching an other game that will last 30 minutes.
Every MMO, regardless RPG or not, will require you to invest time to repeat some actions and pay attention to it as much often as you can. See Travian for example. Screeps will not, if you manage to write decent scripts.
