Nothing about netcode in a sim is not advanced.

Games that have far more forgiving constraints (e.g. shooters, because the phantoms move much slower) have issues when the connection is poor (high ping or even worse, packet loss).

I'm not saying that EDs netcode is perfect, but if you think that a) other games don't have the same problems or b) the things that don't work when the connection is poor are easy fixes, you need to have a good hard look at information theory.
