I really like this game. I like to play online or on the skirmish mode because even on medium difficulty, the CPU presents a decent challenge. I haven't tried any harder than that yet.
I used to play Warcraft II on the computer and this game is different.
The buildings and units build much quicker than Warcraft which means you have to stay on your toes in the early going.
There is less variety of units in this game which I don't know if I like more or less than warcraft.
Also, because you are building, for the most part, battalions, its harder to pick apart your units and the battlefield becomes hectic fast. I kinda like the realism there.
Micromanaging can be difficult for your units but I was never good at micromanaging anyway
It is easy to pick out your heroes so you can use their skills though.
overall a very addictive game.
