I looked at the website briefly and made this list of similarities between the two games: the name, humans migrated to Twilight Forest to survive a "plague", a demon legion is invading the land, Titans shaped the world, there are undead and nagas, there are regions called Moonglade, Coldridge Mtns., The Barrens, Stranglethorn Vale, Swamp of Sorrows, Blasted Lands, and Dragonblight, Alliance buildings look like Stormwind with blue roofing, Horde buildings look like Orgrimar.
