Make All Buildings

Thank you! Worked for me today after disabling all DLC from my game. I tried legitimately for a few days IRL and gave up and found this :)

update, i had to apply a few buildings like the treasure hunt unique ones and the academic library
\

this doesnt work

Guys! I just got this damn achievement! But not with this save. Here "https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=409335954" a guy with the nickname Rovas117 left a simple way - I did as he wrote - ""I Want It All" achievement is still fine.
What do you need to do:
1. Make sure ALL DLCs are disabled. Going PURE vanilla here. This is easier to do if you have make a Skyve profile and just disable everything.
2. Enable Game Anarchy Mod in the profile.
3. Load into the game.
4. Unlock All using Game Anarchy. Plop ONE of each building in the "Treasure Hunt" tab in the "Landmarks Category. It should pop once you place the Plaza of the Future."
It worked!

I tried using Ham Sammich's way as well. Didn't work. Mind you it didn't unlock in my own game either, and I've definitely unlocked every building.

@水木 I just got it yesterday! What I did was uninstalling all the DLCs, and then placed all the buildings (the new parks like the parking lots, the new stations, to be sure the new roads, etc). At first I didn’t get it as well and then a notification popped up about a new building in the road panel. The road tolls count towards the achievement maybe you forgot them as well?

Did follow each step from @Ham Sammich, but got no achievements.
Anyone here that got it from this year? (2023+), from this save-file.

Achievements is just to unlock, and there is only one that was not unlocked yet,
but even if I did unlock it (Academic Library) I could get it.
Did also tryed to build every single building, still nothing.

Hi disabled all the dlc, downloaded the required mods, but didnt unlock when i placed the academic library? Then did a reset unique building and tried again, but also didnt work? what am i doing wrong?

hiyo, just used this save file to get the achievement. Only thing missing seems to be Academic Library. Thank you @T22!

how i did it:
1) uninstall all DLC
2) Settings -> Misc -> Reset Unique Building Unlocking
3) Open a large save game like NY (300,000) or your own large save
4) Open this save
5) Build 5 public libraries (more to get cheev faster)
6) Once you have 300 lib users/week the Academic Library was unlocked and i got cheev.

Got the achievement with this map.

Step 1: Lock previously unlocked buildings (somewhere in the settings)
Step 2: Install this and "Achieve It"-Mod (I installed the park as well, but didn't use it)
Step 3: Uninstall all DLC
Step 4: Unlock the Unique Buildings
