I have flown G3 a little and purchased FS one. I have about the same amount of time on each simulator.

G3 is a much better game.
I enjoyed playing this game more than FS One. It has some really cool features.

FS one is a much better simulator.
It was harder to fly. I got a false sence of accomplishment from some of the things I pulled off in G3.
I was suprized at times to see how realistic the A/C reacted.

Most posts are biased by people who have a loyal comentment to a certain SIM product.
I would like to see some guys out at the field that have never used a sim take each for a test drive. They would be able to give an unbaised review that would confirm the better sim.

I was very impressed with the Blade CX/CP and the added difficulty to flying 3D planes.

Some of the tech support I have read on this forum goes way beyond what I would expect from most companies.

I have one problem...
I have a 3ghz P4HT ATI X1300 PCIE 1gig ram Sound blaster audigy zs2

The sound works but randomly cuts out. and crackles. Lowering settings listed in the FAQ did not work. there is another guy posting with the same issue.

Lowering settings may help fix some peoples problems, but still feel that should not be considered the fix. I am hoping that this is still be looked and a fix comes out in an upcoming patch
