I see what you mean the metaphor has some appeal but ...

In business systems it is desirable to normalize the data, lets just discuss first normal form, all attributes are atomic.

OTOH game objects contain some atomic types but they also contain pointers, other objects, trees, collections ... which is all very non-atomic and very non-normalized.

The internals of a game are more like the internals of a wordprocessor or spreadsheet.

Multiplayer games are typically implemented using a client/server or peer to peer architecture. Only a relatively small amount of game state needs to be broadcast and shared because each player runs their own instance of the game, all the static game assets are duplicated.

Duplication of data in business systems is generally avoided or requires advanced replication management.

Hope that answers the questions.
