Several things come to mind. I will not say most.
And that’s not a simulation, that’s a video game.
Having trained on everything from an old Hogans Alley, the FATs system, up to the moderm simulators, I will say that the video games are worth less than zero in real life.
For the price of one of those games and gaming units, one can get a decent airsoft gun and get some realistic practice and training.
