So what was Age of Wonders 4 like then and now?
It is fun, but it is very different from your usual paradox fare.
It is a fantasy simulator, nothing too complex, but works and isn't too over complicated.
I would call it 4x lite with a heavy focus on actual turn based battles.
You choose a species/traits for your race, choose cultural traits that tie into what magic type they use, and choose a hero. You start with a city and said hero and a few troops.
You kill random monsters, annex map regions, build on them, eventually finding other players and more random npcs. Combat is turn based with you controlling 6 units per army to a maximum of 18 units.
It is a somewhat barebones game for 4x, amd the fantasy combat is a satisfying turn based tactical match that lasts 5 to 15 minutes.
On the plus side, its not hyper political and you can create most of what you want, the selection is pretty diverse.
It isn't super good in graphics, and the campaign isn't that great or long.
So if you want a more casual fantasy sandbox that doesn't need you to do spreadsheets on tank fuel supply lines, its good. You can make undead hobbit conquistadors.
