I am 25 years old and I'm playing strategies more than ever!
Currently I am playing Rise of Nations (extended edition) which is like a 2017 remake of the original game. It is like age of empires but you can play campaigns all over the world.
I love playing this game after all these years because it has elements of total war series (but a lot easier and more interesting), it also reminds on Age of Empires or even Civilization, and most important it has city building simulation elements.
So basically you build your own country, your own cities, boost economy, research technologies, move troops and advance trough ages with all basic elements of some most popular RTS, simulation and strategy games.
