You might take a look at it if you want to be the first on your block to give it a try.
I have G3 and I like it a lot, flying G3 has definitely improved my flying skills. Even a flight sim like FMS with less-than-ideal physics and flight modelling can be helpful for practicing control oriention and the like. You can spend a small fortune on G3, the 5 add-on packs, and the two G3 specific expansion packs. At the end of the day, though, G3 has helped me save my planes at the field on more than one occassion, so it's already paid for itself in my mind.
