Making your game general

ITT we discuss how to collaboratively design our games.

How does this sound? Can this scale at all?
Second Life gameplay but all currency is replaced by Cryptocurrency(mined in background by player) and uploaded assets are stored on the blockchain (cost proportional to size).
Land is created/modified by uploading a special data block that can reference earlier assets and defines territory size/coordinates:
empty land is cheap, adding new assets(content) is expensive, adding existing assets is somewhat cheap(reusing addresses of assets, instead of uploading new things).
