Experience creation depends upon fostering some combination of tribalsim and a sense of progression among its users. This requires good database storage and integration. It also requires a very flexible avatar permission system customizable by each experience. Will these tools be in Sansar? How much of the C# language will be in Sansar as it is a very powerful language when everything is there? And congratulations on noticing this lack of experience creation support in Second Life because it has too many beautiful yet empty sims. People need a reason to buy and create things.
