That massive number of resources, planets, pops, fleets, and everything else is not only understandable but feels magnificent when you have them dancing to your tune. Also my brother in SpongeBob, you literally got mad at a tutorial. On a more serious and hopefully helpful note, the game grows on you like a fungus. It’s really not much worse than Civ. Energy is gold, Minerals and Alloys are effectively Production, Unity is Culture (and works almost identically to Civ V, you can’t use it to outright win is all) and the scinces are well Science. As for all the others, my man those are your Strategic and Luxury resources. But that’s only where the fun starts, the real madness is civ and species generation. I once made space orbital dwelling, advanced robotics having, xenophobic, pacifists that relied on slave labor stolen from nations that declared war on my seemingly defenseless empire. I also made the Megachurch of Dewy, Cheatham and Howe.

Edit: I almost forgot the best terrible civ I made, OnlyStreams.
