4X Starbases for Planets is a mod designed for the popular strategy game Sins of a Solar Empire II, specifically enhancing gameplay by allowing players to build up to four starbases around planetary orbit wells for each race. This significant increase in starbase capacity enables more strategic depth and complexity, allowing for more robust defenses and resource management. The mod maintains the normal fleet supply, ensuring that players can still enjoy balanced gameplay while utilizing the new starbase capabilities.

In addition to the new starbase limit, players looking to further enhance their fleet and logistics can utilize an additional mod that increases fleet supply and planet logistics slots. This combination of features allows for a more expansive and tactical approach to managing resources and military forces, catering to those who enjoy detailed strategy and planning in their gameplay.
