Someone mentioned a marketplace for user created contents. I think this idea is very good, for it would increase the XGold's cash flow and take off developer's tremendous burden on periodically adding new contents.
In my opinion, the developer might want to consider few things if marketplace would become an option:
1. Get XGold cash out as any currency or credit.
2. As more people buying and selling XGold. A fully integrated XGold exchange mechanism with live updated currency watch and so on is required.
3. Release developer kit for free to public. There are lots developers out there, draw them in. MMO games like Second Life, its creators have quite a successful history developing content. Might want to grab their attention by giving out friendly and free developer kit. Who would reject if one give them an opportunity to make more money with little effort?
Just my little opinion on the future of this 3DxChat
