But this is why we reached the Industrial Revolution too fast.
What tech tree? The improvised tech tree? Improvising is not always a good option, especially in this forum game. Maybe a tech tree shouldn’t be implemented when we come back, but it’d be a good idea for future games. To reduce limitations, we could allow the players to add theoretical objects (e.g. alternate inventions) to the tech tree if they make sense.
Also, I feel like it’d be good to discuss the diffusion idea from this discussion (first post, not mine; for future games only).
