This is merely a half-thought idea... The idea is to make it possible for normal people to edit the PS world or at least part of it, just like people can edit in a Wiki.
People could \"experiment\" in a sandbox-like area with creating landscapes, towns and such stuff. Maybe they could even add NPCs and build quests. If someone builds a rich, nice environment, it could be integrated into the \"real\" PS world.
To build areas, there could be some scripting (or merely description) language available. It can create rough landscapes and place pre-made objects (houses like those in Hydlaa, trees, monsters, NPCs) in the landscape.
Wikis have shown quite an amazing potential. In my opinion a similar potential could be used to expand the PS world very quickly. The drawback is of course that the player-created worlds are probably not as high-quality as the dev-created ones.
Thoughts, comments, ideas?
