advanced_galaxy Console Command

The advanced_galaxy command in Stellaris is used to simulate a game forward to the year 2400 in terms of the overall progress of all default empires.

Essentially, it's like fast-forwarding the game to a more advanced state.

Once this command is executed, all the default empires (or computer-controlled empires) present in the game will experience notable expansion and growth in terms of colonies, fleets and technologies, reflecting what expected progression might look like by the year 2400.

This includes:

1. Colonies: All the default empires will gain a certain number of colonies or planetary systems under their control. These can include both uninhabited planets that have been colonized and inhabited planets that have been conquered.

2. Technologies: The default empires will have made significant strides in technological advancement, unlocking new research options, technologies, and technological benefits.

3. Fleets: The size and strength of the default empires' spaceships fleets will have increased, presenting a stronger military presence.

Such features offer a more challenging gameplay for the player as the competitors are more developed and unpredictable.

It is an ideal command for experienced Stellaris players looking for a greater challenge, or for players who want to skip the early stage of the game and dive directly into the more complex later stages of the game.
