So I've come to realize that these years of playing World of Warcraft off and on have blinded me to the truth: I like the Starcraft universe much better. Thank you, Starcraft II, for helping me realize this.
Warcraft (pro): the undead are kind of cool, and I like the stuff they're doing in Burning Crusade.
Starcraft (pro): EVERYTHING
Warcraft (con): too many dragons and elves, orcs and humans are boring.
Starcraft (con): NOTHING
