Is common whatsoever, as well as helpful? Let us say I develop a 2-Dimensional RPG using ORM architecture within an MVC pattern, for instance. Exist benefits?

An ORM is really a typical business software pattern, not something utilized in game. I suppose you could utilize an ORM for loading the amount from the database and employ it in order to save the present status when the overall game is quit. But that would not be the primary focus from the application. An average business application's focus would be to manage data, therefore the ORM requires a central role. In the overall game, the main focus ought to be around the interface.

Utilizing an MVC method of building user connects is nearly always beneficial. It keeps the interface code structured.
