I think many people associate shareware with the popularized apogee model where indeed the games were broken up to episodes
the thing is that before that became a common method many shareware games simply asked you to register and had full functionality
(maybe had a message or a counter or some reminder that you are not registered: like in total commander or winrar )
I'm sorry I should have been more clear about this in my post 😔
what I'm confused about though is isn't pay what you want the same as the donation system then?
and isn't holding back features mean just that you have a free demo?
anyway I guess I just don't get it 🤔
