No words I can write can explain what it is like to play a MMORPG (Massive Multiplayer Online Role Playing Game) better than this film. Included in the movie are the "serious" mission planning systems and l33t mathematical estimations of success. And naturally, the horrorshow (as Alex would say) of including an Aggrohound in your group.
The game being exhibited is the very popular World of Warcraft Game by Blizzard Entertainment.
The clip is very funny, and all I can say is...LEEEEROOOOOY!
