Act of War is not a great game, but enjoyable none the less.
The game is told through a mix of live action and animated cut scenes. Although it was fairly obvious that Act of War was just trying to copy the c&c games, the cut scenes do get the job done. The story itself, while not great, will draw you in enough to continue playing the game.
The game play itself is fairly cookie cutter, although I did find it cool that you could choose to capture POW's for extra cash. Resources are purely monetary. You can also construct a hacker to siphon out funds from your enemies. There are three different factions: The Consortium, The U.S army and Task force Talon although during the single player campaign you only get to play as the latter two.
This game is now a couple of years old but has stood the test of time quite well, you could probably find it in a budget bin. If you are looking for a quick RTS fix Act of War is not a bad choice at all.
