How are we going to handle persistence in the full game, for the most part?

In the full game of the Persistent Universe, that persistence will move out of the client and that code will end up being used on the server instead, in the game servers. And then that code will talk between the game engine and the game code and the persistent services in the universe cluster. And they will handle the saving and loading of it. So it won't actually be on the client anymore.

So whenever you wanted to place your lamp, it would stay?

Yes.
