As an RTS lover I am particularly pleased, if I can find a game in this genre for my mobile phone. Unfortunately RTS mobile games are a really rare thing. That may be because consumers wish to have simpler games for the cell phones, as you are playing the phone while moving and in my experience you need about 5-10 minutes for one level. Of course, this is for a real RTS game too little.
For RTS fans the long duration of the game is not a problem, because usually you may save the game to continue to play later.
Act of War (It is actually a game for the PC with the same name) is basically a simple strategy game. We must build a base here, gather the units and attack the enemy. However, if you are look at the strategy games for mobile screen sizes, we find that Act of War in comparison to other RTS games is quite well performed. A nice pseudo-3D graphics, a large number of different units and buildings make the game for RTS fans really interesting.
