Thank you all for replies!
Of course we have palette of tastes, my is a bit hungry one
For me doasn't matter store is big or small, i like if has some own character. About deco's: filled 'warehouses' are the same what empty ones - they has no visual idea.
Marketplace was already when i log in first and for me this is good way to get something quick (vendors pictures can give a more info thro), in other case i like to wander a bit in world.
I'm aware about costs, but maybe some idea investment would be usefull to keep inworld movement.
