FlatoutATC is an independent air-traffic-control game built by one developer who wanted ATC to be approachable. No 200-page manual, just you, a radar and a sky full of aircraft.
Most ATC sims are deep but daunting. FlatoutATC keeps the decisions that matter: separation, sequencing and handoffs. It drops the busywork, so anyone can jump straight in and feel like a controller.
