Have you considered that you have been downvoted because your response to a simple and clearly trying-to-be-helpful comment was quite frankly autistic bordering on aggressive for no clear reason.

Yes, I considered that, and it wasn't a personal attack, but rather a plea. This was (I believe) a new account and one should, if possible, to read the full discussion first before commenting. If I was on Slashdot, I would probably use -1 Redundant, which tells the GP same thing as I told him manually.

Not to mention, Eco seems to be quite different game to what I am proposing. It might also have the mechanic of exact accounting for resources, but it remains to be seen how rigorous that is.

I still don't know why Eco should not be mentioned. Please give a tldr reason. Haven't played it. Negative steam reviews seems to mostly highlight technical issues. And while that should be noted, does make it a reason not to mention the game when discussion games teaching ecology models.

I thing i did hear about this game a while back and apparently decided it wasn't something for me, even though i liked Factorio. But cannot remember why.

I agree Eco should be mentioned, my point was it was already mentioned in three another comments in this discussion (outside this thread) at the time I wrote the OP.

In any case, I think a game with first-person focus (like Minecraft or Eco) and a game with civilization focus (like Civilization or Sim City or Transport Tycoon or even Factorio to an extent) are very very different style. They might touch same topics, but the challenges are different.

If anything is similar to what I propose, it would be Block'n'Hood (which also has global warming, I believe). But again, the scale is different. What I would like to see is something that would really put, for example, Vaclav Smil's books into a game.
