That level of complexity still exists but in a different form, (modded) Arma3. That has a ridiculous level of depth and complexity that is hard to describe without playing it but hundreds of weapons, vehicles, equipment, a fully modded medical system (CPR, Airway Management), technically accurate radios with dozens of channels, ballistic system that accounts for wind/Coriolis effect). Insanely deep and yet still really good fun to play as a unit.
