I own a physical copy of Black Moon Chronicles, bought it without hesitation when it came out, and played the four campaigns, several times over.
Black Moon Chronicles is a fantasy strategy that mixes real time battles, with turn based campaign map. Each campaign is played on a series of maps where your armies are deployed, which you then move to a series of objectives, purposely fighting or avoiding any enemy regiments present on the map as well.
Each successfull battle nets you gold which you can use to buy units, build barracks and support buildings .
The battles are either encounters with enemy armies, fought on a random map, or fought on a scripted scenario, these last ones progressing the story, or granting you extra gold, or having some effect in a future engagement.
There is no limit as to how many units you can bring to a battle. This game's selling point were the huge battles you could have, and some I'll admit have that sense of epicness. A shame the AI is poor,not even managing formations well.
You have four factions to take control each with their difficulty setting, and playstyle. Magic is present and very powerfull, as the AI is lackluster to say the least. Each faction has their own flavour and uniqueness, that requires you to change strategy. But overall the game is not hard.
You can even easily tweak the game to your liking, by editing a few file with a text editor. For instance I would generally tweak the damage of the archers for my campaigns.
As with all Cryo games, the visuals are stunning, holding up even today for my standards atleast. Storywise you will be lost unless you read the comic books where the setting is based from, but essentially you are the child of prophecy destined to become the next emperor.
If you fancy strategy and would like something different give it a go. I have been secretly wishing to see this title on GOG for a very long time.
