My main focus on my mods will be staying in tune with the current G2G balance mod, and give more content close to what the game already has.

Combat:

Railguns (short-mid range projectiles maybe as a tier 4 special module anti-carrier weapon), a couple of modules, Techs (for armor and air units), some traits,  for armor and air units, tier 3-4 defense buildings.

Quests & Exploration:

A ton of quests, an upgrade for Exploration ships.

Minor Factions:

They would use bonuses from my "More Population Bonuses" mod, for example a minor faction that gives 15% Dust on 20 pop. and helps with dust inflation when assimilated (something like 10%).

Technology:

Science (more stuff for tier 4-5), Empire (more religious buildings that give happiness and influence), a tech with reverse terraforming (AKA I need more desert planets)

Any idea is welcome!

Quick unrelated question : Do you think it's possible to add another science tier ? (or a science tree)
