I've wanted a more accessible combat flight simulator. Something like DCS or Falcon BMS with realistic flight physics, but more arcade controls (the aircraft should handle realistically, but I shouldn't have to spend 20 minutes starting the aircraft and pushing simulated buttons and switches in the cockpit, even though I have a great appreciation for that level of detail). I don't want my aircraft to have 99 missiles…
Do you recall "Onslaught Mode" in Unreal?
