But you seemed to be very concerned about losing popularity, and downgrading to a hobby level of development would certainly do exactly that. If, for instance, you ended up not making much of a change in 6 months, I’d say a majority of people would probably just shrug and say “Oh well, I’ll just check back in a year cuz there’s nothing new to do.” If that’s fine to you, then there’s nothing wrong. I understand that it’d result in your own happiness, which is great, but I think that would ultimately kill the game.
I think the last option (making yan sim a hobby) is probably the worst idea out of the choices you outlined.
