@onghyr If you've done the tutorial and economy playthrough from Singleplayer you can continue to Skirmish maps and do Scenarios. Its basically like half baked campaign, during that time you can increase AI difficulty once your comfortable and being able to beat easy ones. Just disable Treasure and if you want to improve your gameplay setting 200 pop can help to understand your limit.  Single Player > Matches > Scenario > Default/Naval Maps > Arcadia(The first map). Once you complete then go to the next. After completing that, experiment and choose a Civ you want to play. Afterwords you can transition to Map Type > Skirmish. At this point can watch general replay how people boom by being efficient and using batch training. Watch on Youtube, Replay Pallas, Multiplayer then compare it to your replay against AI. If you get bored then Go to Map Type > Random. Once comfortable you can try play with others in Team Game, you'll probably lose. But before that install Feldmap mod to prevent missing dependency and if you want install Community Maps mod, for more... maps. Got'em! Being able to reach 100 pop in around 7 minutes is a good indicator your a good player assuming you don't get attacked also depends on map. My limit for citizen on fields is 40(200Pop)-60(300Pop), economy is important to be able to do any playstyle. Hotkeys, especially Control Key, Call To Arms. Order One Unit, Select Idle Unit, Select Military/Non Military, Patrol, Select Wounded Units, Garrison, Capture, Attack Units Only, and such is useful so place them, where your hand can reach. Thats all I can think of... I like editing my comments so ideas are on the go here.

I’m completely new to this game and still trying to understand the basic mechanics and strategies. Are there any tips, beginner guides, or common mistakes that I should know about before progressing further? I’d really appreciate advice from more experienced players to help me get started and enjoy the game more.
