What is usually reccomended for a player new to this game with zero knowledge of how things work or what to do?
Start your first game or three with Real Stars and all of the other settings on their defaults (feel free to change the name of your empire, the theme lists, etc).
Before you do anything else in your first game, spice it up by turning on Spacemaster mode, selecting either Mars or Europa, then adding a random alien ruin to it. Then turn off SM mode and begin the game. Ruins can be a lot of fun, and it’s nice to find them right away so that you can get your xenoarcheology units set up.
You’ll have plenty of questions, but all of them have been asked here on the forums before. Usually in the Academy forum, but a search will turn them up wherever they happen to be.
