Warcraft 1: Orcs, they are funny as hell... humans just bore me, and uterly weak
Warcraft 2: Still orcs... same reason, and getting oil is hillarious with those guys
Warcraft 3: 1-Undead: who doesn't like a self developing city, or the necromancers that can rais an army from the graveyard within seconds
2-Orcs: Ultimate melee no competition...
3-Humans: speed building, but weak infantry... the knights rock though
4-Nightelves:bloody hippies... no heavy offense... melee sucks, and chimeras are a disgrace to dragons
World of Warcraft:
-Tauren are not in the original Warcraft lore, but they are absolutely majestic... have you ever seen thunderbluff or the territory around? its the most beutiful of all starting zones... a bit too big, but its fantastic
-Bloodelves are simply awsome, cause they are the only paladins in the hord, and cause the chicks are fine (but not as good as the dranai)... and because they are totally NOT cliche... elves are generally frail weak and nature freaks, but these guys are grude wild strong, and they likes the fat orcses =)
