- Community Announcements2026-08-09 GHG Factory adjustmentThe previous update introduced a major nerf to GHG because it was physically nonsensical. This went a bit too hard however and the factory became far too weak. I am compensating for this nerf by buffing the ghg factory a large amount.
- Community Announcements2026-08-07 Weekly UpdateLast week I updated the climate model to accommodate phase change heat and I said it was a mistake. It was a mistake. We've had so many climate-related issues this week. I need to apologize for one of them : runaway greenhouse effect from water was far too common. This update rectifies this. It also includes a large nerf to safe GHG. Not really because it needed nerfing, but because it was just...

- Community Announcements2026-07-31 Weekly updateThis week might look like a fairly small update, but I actually worked very hard for 3 days on some large rework of the climate model under the hood. While my goal still is not for a completely physical model, I did want to get a bit closer to realistic. I wanted to enable a new optional difficulty setting that accounts for the energy of phase changes. Indeed, evaporating water actually cools i...
- Community Announcements2026-07-24 Weekly UpdateNow that the dust of the Steam release has settled a bit, we can go back to weekly updates. As is tradition, new content this week in the form of a new simple advanced research. Modding took a lot of effort this week... and I do not know yet if this effort was worth it. At the very least it was worth trying. Time will tell. Thank you all for over 1000 copies

Why Terraforming Titans mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Terraforming Titans mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
