I've been playing this game since the first Module called Lockon had a lot of fun and since DCS took over they have added many new modules.
The terrains are great but the aircraft and AI are Plauged with problems,
Weapons don't lock on to targets, systems not displaying what they should,
Enemy Ai have unrealistic accuracy and instantly lock you up.
There is a game mode which is outdated and lately i cant find any way to change joystick bindings for it.
Be prepared to spend at least 50 to 60% of your time mucking around with the constant changes that DSC make and this often requires relearning Systems.
If DCS can stabilize this sim/game it would be a lot more enjoyable.
