The real world is more of a team approach and most game sims have a pretty distorted view of reality. The guy who's doing ground taxi control at a tower doesn't usually moonlight at simultaneously running approach control while also simultaneously running departure control and enroute. A dude running approach 200 miles away usually doesn't get to play tower 200 miles away to tell a plane when they get to take off.
In my experience with aviation and ATC games, I haven't found one yet where the game designer was a pilot or ATC or listened on a scanner to pilots and ATC during the design phase.
I've also never seen a sim that handles dynamics for anything but planes. Real ATC is all about handling very local weather, and NOTAMS, and hot/cold MOAs (military training areas, if cold you just fly thru, if hot you get out of the way or get shot down). And of course it changes in real time not just once at game start. Also you trade / share space with other ATCs, so that dynamic would be interesting. And your shift doesn't end when all the planes land, you'll always both start and end a shift with planes in the air.
I don't expect much from the arcade games but there have been some sims out there that at least graphically have tried to look realistic and have at least sorta realistic procedures and limitations.
