Although I'm really impressed by your work (I know what it is to spend so many years on a "side" project), I can't help but feel that in this day and age of global climate/environmental crisis, making the apology of "10000 tons of diplomacy", "resource consumption" and overall expansion at any price is a bit, well, unfortunate. I think nowadays indie games are strong enough to carry a message....
This sounds to me a bit like saying it's unfortunate that shooter games are violent, or some forms of music satanistic.
Don't get me wrong -- I'm all about sustainability -- not in make-believe worlds but in real life.
I like exploring the awesome power of mechanisation at grand scales in a safe way, inside make-believe worlds. It's a way to learn about it without wrecking this one.
