Why would they want to protect the career mode? It’s a non-competitive single player game. Makes no sense.
The essence of flight simming is modding.
BTW the “career” is meh. Having close to nothing in common with how real aviation works. Zero flight planning and decision making, just following the magical blue rectangles drawn in the sky.
The missions are totally scripted, takes mosty of the fun away for me. I’m not a robot, I want to plan the flight and make decisions, not be a neuron powered autopilot.
Cringy dialogs written for a 5 year old… Way to easy certifications, a traffic pattern for PPL, really? What about dead reconning navigation, simulated engine failures, stall recovery, deep turns, flying through controlled airspace, etc…
Plus funny issues like forcing me to fly through restricted airspace (blue rectangles) and then punishing me for it
