Even though I've played a lot of military simulation "games", DCS has evaded me until now.
After some recent research on armored warfare games, DCS's Combined Arms looks very nice. Another EA game is Gunner Heat PC that's had my eye for about a year or more.
DCS has a lot more to do vs GHPC. I can fly planes or ride/command MBTs. I just watched an informative vid on how to control the MBTs.
I played all the early tank sims from M1 TP, Armored Fist, T34 or Steel Fury (Graviteam iirc), SteelBeasts (all), and others ( I didn't mention WoT or AW due to the arcade-like play style but ... those too).
The only combat flight sims I've played were IL2 and LOMAC (an earlier Eagle Dynamics game). In DCS I can fly a P51 for free. My favorite air asset in LOMAC was the A10; so much fun to attack ground targets.
DCS may be a future download if I can convince myself to quit playing other games during my limited gaming schedule.
have a nice day
