Noticed this achievement in Borderlands 2 the other day... it's a World of Warcraft homage! Originally For the Horde! (Said by orcs, and used more widely by Horde players as a saying.) So, yes there's a lot of homage to lots of things in games (like I have a lot of EQII in-game homage here), but sometimes games reference other games. All culture is fair play (emphasis on play).
