Non-Player Races (NPR)

Non-player races are your computer controlled opponents. They have the same tools available to them as the player, with the exception of their ships not needing any fuel.

Racial Tolerances are randomly determined, but basically, there are oxygen breathers and methane breathers. Research strategies and ship design also procedural (i.e. random), meaning that no two NPRs will be the same.

Sometimes two NPRs will fight or do actions where you can not see them. This leads to turns getting cut short, possibly down to 5 seconds. Typically, these periods of shortened turns will only last a short while. See Game Slowdown.

Aliens

You turn off all alien incursions during game creation

Precursors

The Precursors are an ancient robotic race that dominated the galaxy until they were defeated by the Invaders. Since then, they have fallen into decay and all that remains are few isolated groups of robotic ships that guard the ruins of defeated foes waiting for new instructions that never arrive. Their mission is simply to eliminate all non-Precursor life.

Precursors robotic ships guard some of the alien ruins and occasionally random encounters with small Precursor ships maybe created in non-ruin system. They have no real populations, although they may have small listening posts and weapon caches in the system. Although few in number and they don't have any survey ships for exploration, they are likely to be higher tech than your own Empire at game start and any starting NPRs. You will need to overwhelm, outsmart or simply avoid them until you are ready. Leave this selected as Precursors provide valuable combat experience. Rather than a complete Empire similar to your own (which is what NPRs will be).

Invaders

The Invaders are an ancient extra-galactic race that defeated the Precursors civilization during their last invasion. They are always hostile, very high tech and extremely dangerous. For a starting game, its best to disable them so leave that box unchecked. Also beware Invaders tend to explore a lot, causing the game to become slower.

Star Swarm

An species of living ships that reproduce in space. Individually they are weak, but can be very dangerous in numbers.
