CyPhErIoN: Groundcontrol 2
just the name makes me want to play it again :)
I've played the full campaogn about 3 times through and it's a quite unique setup compared to most of today's RTS. I really enjoyed the fact that you could merge your entire army almost.
Starcraft 2 uses this with the protoss as well :)
Most RTSs allow you to combine your troops but I read somewhere that one of the factions can put two of it's soldiers together to make a third different soldier. Not sure if it was GCII or something else (been reading a lot of reviews lately).
What totally flipped me out is that you can send your troops to take cover in buildings and fire from blasted out windows.
I also liked that the troops felt very easy to manage and sort out. I did notice that it is easy to leave behind a trooper if you didn't switch him out of a stationary setting when you moved your troops. Easily rectified if you studied your mini map and saw the little stray green dot but there is quite a bit of micro management to remember when repositioning and moving.
I also noticed that the directional command isn't very responsive. In this instance of your vehicles with rocket turrets, they have tougher side armor so when positioning them you want to turn their side to the enemy but right clicking and dragging made them simply move again more times than it actually worked to reface them.
Small complaint though because, if you're like me, you usually just swarm the enemy with a large army and don't worry too much about who is facing what way.
