Warcraft 5 was going to originally be Warcraft 4, with the return of the Burning Legion and the Journey to Naja'tar in the Maelstrom, I changed my mind to that and called it Warcraft 5 since Wc4 is already being announced. The campaign starts with Undead, then moves to Human (Under attack by Undead), Orc (Aids human), and Night Elf (Escapes to Naja'tar).
Warcraft 2 is pretty much the Orc levels from Warcraft 2: Tides of Darkness, they're alright, but the first mission is having trouble (Finding out how to make the 4 Farms/1 Barracks/4 Grunts Objective)
