Massive happens to be the name of the crowd animation software used to spectacular effect by Weta Digital in the Lord of the Rings movies. Popular Science magazine has published an article on Massive.
Speaking of massive crowds in Middle Earth, what will ever happen to Middle-earth Online, the MMRPG that was touted last year? Not much besides lawsuits it seems.

Middle-earth Online, a massively multiplayer role playing game, was announced in mid 1998. Nearly a year later, Sierra underwent a reorganization, which resulted in the cancellation of several game titles and the restaffing of the Middle-earth Online project. Since then, Sierra Studios has been tight lipped about the progress of the game but has repeatedly stated that it is being worked on and that new staff is being hired for the project. The current state of Middle-earth Online is not known at this time, but we'll keep you updated as things develop.
