Fewer Nebulae
This mod does three things:
- Reduces the percentage of battlefields nebulas spawn in,
- Doubles the area of the battlefield,
- Planetary defenses no longer spawn in the middle of the battlefield.
Previously there were 5 battlefield types, having 0, 2, 4, 6, and 8 nebulae respectively. With this mod it’s changed to 0, 0, 0, 4, 8, so nebulae only spawn in about 40% of the battlefields instead of 80%.
The 5X mod already does the 2nd and 3rd thing, but not the first. This should work with other mods, but you should put it near the bottom of your mods list in game for best results.
