Act of war direct action is one of the brilliant strategy game ever made for me.Probably I must have played this more than 100 hours at non-steam version when it was first released.It's scenario was inspired from Dale Brown's stories (Who is well known military novel author like Tom Clancy).If you like Tom clancy style scenarios or series like 24,homeland etc you will probably like this game.
AoW:DA also looks similar C&C titles,building base,gathering petrol resources and producing units to crush enemy.Cutscenes is one of the best part of AoW.Which made with real actors.On missions a little video screen appears on the corner and begins to inform you about mission and shows news just like C&C.You can capture wounded enemy soldiers as a prisoner and sell it.
Game changing shape according to missions.Sometimes you control small tactical units to eliminate enemy forces or sometimes building bases and producing mass armies.
As far as I read around, some guys complain about that game doesn't work on windows 7 64 bit and more than 2 GB ram.I run windows 7 64 bit home premium and have 8 GB ram,I haven't experienced any problem with game.I just installed and hit the play button it launched.
Edit:A patch has been released for game to run on win7 and 8.1
+excellent graphics (compare 2005's titles not todays)
+C&C style videos
+No unit limitations
+never bored (it depends on you of course :) )
-doesn't have widescreen support.(there is a mod on moddb which adds widecreen res. )
As a result 10/10. Now I can't wait for Act of Aggression.
