I've just recently gotten FC3 working due to a payment glitch that wasn't (ticket submitted, they can take their time on sorting it out), and while I was honestly expecting a little more 'warthog' from it, I'm not disappointed. If you try to do an unrestricted takeoff in an A-10 it just kind of looks at you funny. Take an Eagle or a Flanker with a light load and you can stand them on their tails and grab sky like it's going out of style. Having access to more planes for more roles is always a good thing, and if I have the desire to play in the pit, I can always jump in an A-10C or Ka-50.
I only wish the Su-27/33 could mount more Air to Ground weapons. I remember playing with the Kh-31s and 25s in Flanker 1.0 and they were great fun. Also the thought of launching the big Russian anti-ship missiles, like the Moskit and Kingbolt does fill me with a certain amount of lust.
