Bobat have you seen The Lord of the Rings?? Well, WarCraft is heavily based on that.
It's a strategy game like StarCraft.
In WC3 there are 4 races: Humans, Orcs, Undead and Night Elves, with all their own special units.
It's fully 3D, has a very good story line and quite some gorgeous pre-rendered and real-time movies.
What else is there to say?? It's a great game!
