Basically, it's like Unity or Unreal3 or one of the hundreds of other game engines out there, in that it significantly lowers the barriers to entry for the VRMMO market by making crucial tools and middleware freely and easily available - hence the proliferation of Seed-based games later on. An added advantage is the common save format which makes it possible to transfer characters between Seed-based games (but actually there is nothing complicated about that, any two MMOs/RPGs/whatevers today could be made to do the same thing automatically rather easily, just that most games normally do not support such a feature).

Yeah, that's what I got out of that too.
