Age of Wonders 3 is a fantasy themed 4X game, it's notable for having combat that doesn't suck and is actually quite decent for the genre. There's not much to say beyond that, the setting is super generic and I lost all interest after the magic lizard man started preaching about social democracy. I think the random scenarios are the best this game has to offer because the moment to moment gameplay is the strongest aspect about it.
The UI is also a bit archaic so I would recommend learning as many keyboard shortcuts as possible. The underground layer can fall off a cliff for all I care, I hate it.
They want you to make a third party account too so that sucks, but thankfully it's completely optional. I wish I could say the same for other games published by Paradox.
To summarize, Age of Wonders 3 is alright.
