Commercial means money. So if you accept money that is commercial.
The following questions immediately arise: Is studying at the institute an income? After all, students receive a stipend. Is teaching at a school or an institute a business? Teachers and professors get money for lectures and lessons. These are quite practical questions of direct relevance to my project.
I am not yet ready to talk about my project in full, mainly because of the difficulties of translating many terms and definitions of concepts. But in short, my project is supposed to be not so much a game as a scientific entertainment - "learning by playing". I want to devote all my time to it, and sometimes I just want to eat. Yes, and to buy a new computer to work on the project would be nice. There are already people interested in the project and ready to help, but they too want to eat sometimes - how to pay them back? The game itself is supposed to be distributed free of charge, without mandatory payments in any form.
I define the project as "Socio-Economic Constructor-Simulator" (SEC[K]S for short) :D [how can you communicate in a language you don't understand how to read a letter?!] .
