I really like the concept behind the server, with the ruins to be explored and solved and such. The story part being singleplayer is an interesting twist where multiplayer is opened upon completing the story part, and no economy? Interesting. The simpleness you find in several other good RPGs, you have taken that and adapted that simpleness, which is a good move,keep it up!
As I said, keep it up, wish I had gold and could help
Good luck with the server.
