Thank you for that information. Regarding your statement "When the next version comes out we'll only be going up to, but not including, the Steam Age...", in the current version, the only object that I think could be included in the "Steam Age" is the Steam Bot.
I recall that in other postings you have said that for the next version, instead of Basic Bots and Steam Bots there are only combinations of the 3 bot parts: Head, Body, and Drive, each of which could be different "Mk" versions. I liked the Steam Bots in the current version because they did not need to be "wound" and they could collect the fuel that they need to run (such as logs) by themselves rather than depending on others. In my game, I set up Steam Bots to do all of the winding of the Basic Bots.
In the next version, will Bots still need to be wound by others or can they somehow get their own fuel similar to how the Steam Bots did?
