Real Flight G5...
I used RF 2 and 3.5 and found them to tempting to just play with as opposed to using it as a true simulator. Now with RF 5 they are offering "Combat Events". Well if it's RC combat, you know the chasing streamers, that would be good and make better pilots. But they decided to make it a video game. There are plenty of air combat video games on the market with better (realistic) flight models for the full size aircraft. I think it's just rediculous and defeats the purpose of the simulator.
