Correct me if I'm wrong please gents...:
Eagle Dynamics are the devellopers for Lock On, Lock On Flaming Cliffs, DCS Black Shark, Lock On Flaming Cliffs 2, DCS A-10C, DCS Black Shark 2.
Original Lock On: Modern Air Combat has A-10A, not C, but in much less detail and fidelity to the real aircraft. Ubisoft was only publisher for Lock On: Modern Air Combat, they pulled the plug on the product after that. Lock On Platinum is a patched version of the original Lock On: Modern Air Combat game.
The DCS Series is a much more in depth simulation of various platforms, with 3D, clickable, 6DOF pits, and is in constant devellopment.
Hope it helps you figure it out a little :)
