Welcome! Its good to have more people interested in theorizing about the gameplay. It is important to remember though that we are getting quite close to the end of the Microbe stage roadmap (Release Roadmap - Thrive Developer Wiki), so we are less likely to do any major revamps of the Microbe stage. Us finishing the Microbe stage this year won’t mean that we stop all development of it, it just means that our focus will be moving to the Multicellular stage. This is an example of a recent thread that resulted in a change in the game: An iron thread.
Is there any particular stage you are most interested in? While the microbe stage is the current focus, we will ‘soon’ be switching to focus on the Multicellular stage with the release of 1.0. And Macroscopic stage is not too far away either. Discussion of the later Awakening, Society, Industrial, and Space stages is also always interesting as well, though it will still be a while before we are able to focus development on them.
