Cities

The cities, like mentioned in the Game World section, would be best to be instanced, this is for two reasons:

1) Instances would help to ease the server load, thus making it possible to create bigger and more complex game world.
2) Future changes to cities would be easier to make.

I currently have 3 ideas of what would happen when you go inside a city instance:
1)When you enter city, your car is stored in carage, and city itself is just a picture/map of the city, where you click where you wanna go.
2)When you enter city, your car is transported inside and you drive around the city to get to the stores etc. where you want to visit.
3)When you enter city, your car is again stored to the carage and you get to travel around the city on foot with your avatar. This would be nice, cause it would also bring avator customization to the game

Best would be some kind of combination of all three. Maybe that first you drive through the city, go to the building, park your car there, use you avatar to move through the building and finally when you enter a shop it would be a single picture of inside the shop where you select what you want to do.
