Currently in beta there is only one difficulty for computer controlled AI. It is set to very easy. It is like this for two reasons:ZippyDSMlee said:I dunno why people say this WC3 was bad....sure MP side was good but the SP side was well....."bioshock" easy due to the crappy AI they didn't take the time to work on or polish....
To encourage people to play against eachother instead of computer AI's.
Because this is beta, and there will be sweeping balance changes. They do not want to be adjusting how the AI plays every time there is a patch.
There will be 5 difficulty modes for the AI: Very Easy, Easy, Normal, Hard and Insane. The Insane one cheats a little, but it is not designed to be fought unless you want a real challenge.
Also, there will be several difficulty levels for the single player campaign, and many side levels and all of them include optional missions that add difficulty and replayability.
I personally liked Warcraft 3, and all aspects of it. And that is because I didn't compare it to Starcraft.
