All of that outlined in my list was about the integral Gamespy network. VATSIM is for professionals. Gamespy is mostly used by kids, as outlined in someone else's post.Example:In VATSIM, you find VA meets and pilots (the massive heavies), professional pilots, real-life and wannabe ATC-ers, and the occaisional pleasure pilots and noobs (GA). In Gamespy, you see noobs, kids, and those who just fly for fun. (e.g virtual aerobatics squadrons, GA planes and fleets of F15s/F14s/F18s who attack you, as outlined in someone else's post).Hope that clears up the fog, Ben.
