Not just Parallel to the usual gamer group, but also so far removed from it that we can't perceive its existence, outside of a few ripples it causes.
I've watched a few videos of these simulators on YouTube, and I really can't see why someone would play these games. Simulators of more glamorous or exciting jobs (pilot, fire fighter, police and so on) i can understand, but Road construction simulator actually managed to look less interesting than cleaning my apartment. What kind of person suddenly gets the urge to play a construction worker, on a computer, when all you do is some very mundane tasks?
