I just got into DCS about a month ago and I'm getting ready to buy a module or three. Leaning towards FC3, Combined Arms, Persian Gulf Map and/or the Mi-8MTV2. I've read that it's better to be proficient on one plane/heli and go from there. As opposed to buying a whole bunch of aircraft. Any advice on what I should get, or any input on the above mentioned modules? BTW, this game is incredible!!!!
