it's annoying how he thinks his game play skills are unique to this dimension. they have games too, far more advanced games, and they have extremely high-tech simulators. MC did not face any real life or death situations in the game and neither do they need to face those in a far superior simulator.
Most games balance realism with entertainment(non-realism to make it more enjoyable) for a reason, so his game play hours (experience), other than the lore turning into a goldmine of info, should be far inferior to simulator hours.
