I agree, this is the first RTS I've actually enjoyed playing on a Console. I am a huge RTS fan and the game has enough depth, even in the demo, to keep me interested. Also, the game isnt straight Rock-Paper-Scissors like most RTS. An air unit can easily kill an Anti-Air unit if the owner has upgraded it more and uses special attacks effectivally.
One issue I see is how easy it for me. I am not sure if it is just myself being good at RTS's, or the game is just that easy. I have played and beaten the skirmish mode on the demo with both the humans and covenant on Heroic (Highest mode available on demo) and did not run into many issues. I found that the computer really liked to rush early on Heroic. So I just started with 2 turrets turned into flame/plasma turrets and made 3 warehouses in the back of my base to boost my economy early. Since the AI spent all his money on troops, he has non-upgraded warehouses and low amounts of money. The turrets kill the attackers easily, especially the medium turrets, and if you are the covenant and have Regret helping out.
Anyways, I found that either the Orbital Attacks (MAC Bomb) are too weak, or the Hero Units (Regret) are too strong. My fully Upgraded Regret VS fully upgraded MAC gun, and I always win with Regret. A full uipgraded Regreat took down my enemy's whole army once. He has huge Plasma Rod Canons, 2 Sentinal Guards, Awesome Beam of Doom, He Flys, and has personal shields. Not to mention if I bring in 5 engineers to heal him so much he CANNOT die to anything less than ALOT of uber units fully upgraded.
Just my 2 cents, I'm actually excited for this...suprisingly.
