For the spawn, my idea is that you spawn in the middle of a city, kinda like New York City. Or you can start off inside of a plane...kinda like you just arrived at an airport, like you just got off of a plane from far far away. In the city, called The City, There should be skyscrapers, and further away we can make it so there is a kingdom. Full of Castles and Dungeons.
For the shop, my idea is that it is a mall. There is a different shop for different blocks. Also there is a food court where people can buy steak, cake, eggs, milk, etc.... I think people should be aloud to buy shops on the 2nd or 3rd floor and they can put whatever they like in there.
I would love to help build my ideas if anybody is interested btw :]
