unity and databases

I have some question about making a multiplayer game in unity(free version)

  1. can I use www class with standalone game and not the web player?
  2. If I use the web player can I load only part of the game, instead of all the 3d assets which will make it a big download?

thanks

1) Yes

2) Not really. For that you really should be using asset bundles, which I think are a pro only feature. You can maybe work around it by using web player streaming but it probably won't work well for mulitplayer games since you have a nondeterministic level order.
