ED also announced (well, said on a forum),
Once the Nevada Terrain is Done (Once they update DCS World Core and release the Nevada DLC), that the engine will Allow Terrain Modules.
So,
Individual Aircraft Modules (P-51D, A-10C, SU-25T[FREE], KA-50, with dozens more on the way).
Grouped Aircraft Modules (Flaming Cliffs 3).
Grouped Ground Vehicle Modules (Combined Arms).
Grouped Operation Mode Modules (Combined Arms).
Ground Terrain/Theatre Modules (Nevada)
3rd Party Non Certified Mods (F-16, F-15e[not IRIS's], etc).
I started to make the switch back in Feb. When i got A-10C for $12, then with the announcement of DCS World and 3rd Party Modules.
not to mention the direction TW is taking, and the responses to members (though some of the members provoked him.).
