That has been known to happen for so many.
Best thing is to work out needs to be in game and you want it to be in game.
If you have not already I recommend you work out a roadmap with everything you need to be in the game and some kind of timeline to finish.
Anything extra can be future game updates for what you feel is not a need.
The game I’m working on I’m expecting to be done by Q4 of 2023. I worked out as much as I can in my roadmap. For the short term 6 months to a year I try and have exact details and dates. Beyond that I have loose ideas and timeframes that get updated when I can better dial them in.
