As the title says I happy to see this game being made, but after looking over your goals I'm concerned about one main thing and that would be the player owned vendor system. The Idea I have always liked (not a huge fan of limitations) but like a lot of people I'm by no means new to the MMO world, almost all player ran stores I have seen in games have crowded the streets or completely open the door to gold farmers. I am just saying if your going to go that route with player ran stores please put a lot of thought into it before hand.
