Diablos story is such crap. Hmm lets see, Diablo was put into a stone, he corrupt some unimportant guy, diablo was stopped in Diablo 1, theres Diablo 2.
Starcraft was kinda boring because of the gay Xel naga and making the races. i never got through the entire story, so i don't know how the terrans split from earth, or how the Toss adopted the Kahla or whatever its called. I read the zerg, and the betray of the Xel naga by the Overmind.
Warcraft Storyline was cool. The four races have unique back ground. Think about the Humans and their aliance, not the greatest. The origin of the Orcs, with the damning of their race, with the pact between Ner' Zul and Kil'Jadan(i son't know the spelling). And how the orcs were truely corrupted by Grom Hellscream, and the drink ing of Mannoroths blood. Then theirs the Night elves, with the War of the Ancients where the Highelves Betrayed the Night elves and sided with th leagion because of the corruption of the moon well. Then the breaking of the continents and the exile of Illidan and the world Tree. Ultimatly, the Best is the Undead origin, where the Orc Ner'Zul by the end of the second war, betrayed those other orcs who followed him into their ding world. He was in the world between worlds, where Kil'jadan attacked him, and made him into The Lich King, and his dark warlocks inoto lich's. Then where he has an immense war with the Nerubians and corrupted the human archmage who brought the coming of the Necromancers. Then with the rising of the Frozen bones of the once mighty dragons to become Frost Wyrms.
Warcraft turely fulfills my every wish in a game storyline, betrayl, corruption, an immense storyline, magic, Demons etc. I could go on for hours explaining the entire story, the corruption of Medivh and the opening of the portal, or the telling of the first war and the second down to the biggest battle. and this is just from memory, if i had the book ith me...
