Far as I know, we're all over 18 here. (Some of us were 18 decades ago.) And most of us are well versed in the flightsim world of affairs.

I've owned at least a dozen flight sims, spent thousands on flightgear and upgrades, and have thousands of hours on flightsims, everything from FS98 to Falcon 4 to CFS1 to FSX and one thing I know for sure is that no one ever made me use even one sim or add-on and didn't want to and never, not once, did a sim or add-on someone else was using detract from my fun flying what I was flying.

Everyone flies the way they want to and dat's dat.  8-)
