Realflight G2 is not worth the money when a simulator like FMS exists. The only thing that looks nicer on it, is the exhaust smoke from the aircraft.
I would rather suggest you to change transmitter/interface/joystick than to change simulator
If you just want some controlling- practice, there are a lot of cheap quite good 4-axis USB-gamepads on the market with analog sticks. And those you can use for all kinds of games too.
