Hi, I enjoy playing Democracy 3 especially with mods.
So I found some of them on mod master list, and some in mod threads.
Here is my list:
Celebis Complex Mod by Celebi
Corruption Mod by jaco335
Cycling Infrastructure by MattJackson
Department For Education And Families by Elinor
Disasters and Emergency Situations Pack by Elinor
Electricity Mod by bankrot
International Culture by francopc
LBGTQ Rights by Elinor
Monetary Policy by DanFir
More Policies by Ulq
Propaganda by jaco335
Economic Realism by Plankicorn
Religious Policies Pack by Guidrion
Sex Education by Cliffski
State Programs by jaco335
So yeah, I have nice 15 mods installed, and there was only one conflict, that was already pointed in education mod.
Are some of them obsolete? Do some of them should interact or be absorbed?
For example there is Corruption mod and Celebis Complex Mod - they both simulate corruption, but it looks like they could be merged.
Or another one, that has basic income policy (More Policies probably), I think it should interact with Monetary Policy causing inflation…
Oh also I noticed, that some mods are WIPs like Monetary Policy.
Also keep up with work, guys 
This thread can also serve as another balance/gameplay mod list. I think these are all such mods in this forums btw 
Sorry for my English - it isn’t my native language.
Edit: Game started to crash, when I press next turn…
Edit 2: Apparently Celebis Complex mod id incompatible with rest, idk which one.
Edit 3: Celebis Complex isn’t compatible with Sex Education (same policy but different effects), Corruption (Celebis has it as situation, while jaco has it as simulation) and energy mod - idk why.
