Now check it and take it from the penguin up south, single player is horible and boring. Then you got Bnet online play. THATS WHERE THE MONEY GOES. I mean if u only know the thrill you get when your fighting a boss with 3 other ppl on ur side 50 levels more then you. Its especially cool with all the magic and seeing the armor and weapons you actually equipt. Now, im thinking it will be another quake 3 arena for me, ill get tire of it sooner or later. SO FAR THOUGH...its very fun ONLINE... so u might as well not waste 1.5 GB on the full version(both single and multiplayer) and just install the multiplayer(online)
