Warcraft 3 isn't due out till 6/25/2002, while only 5000 people were allowed in beta a few weeks later people figured out how to play their own beta. So now theirs a official warcraft 3 beta and a unofficial. Both really do the same thing which is test the game before its final release to get out all of the bugs, but since blizzard didn't allow a few million people in on beta, people result in using the unofficial.

For those who don't know what Warcraft 3 is it is the first RPS (Role Playing Strategy). Its a lot like Starcraft and Warcraft 2 except you get hero's which can level up and get items. The game isn't as fast paced as Starcraft due to you want to level up your hero's since they do very good damage and effects / spells.
