This reminds me of the BMS vs DCS discussion on the DCS forums...
WHO THE F**K CARES!
They both have their pluses and minuses... but they both are striving for what I want... combat flight sim... plenty of room on my hard drives so why cant we all just get along and enjoy the fact that there is more than one option in the combat flight sim world
I have ROF, CloD, DCS and BMS installed currently, pretty happy with that variety myself
