Here is an overview of the game, via its Steam page:
The Touhou Empires is a real-time strategy simulation game (RTS) in which you lead Touhou Project characters and fairies with various abilities to fight!
Players command Touhou Project‘s characters and fairies to complete the prepared missions while responding to ever-changing situations!
The game flow is as follows: players collect resources from the map, construct buildings to expand their own camps, and organize their armies to advance and march. Then, organize your army, march forward, and battle the enemy to complete the mission!
The deciding factor in the game is the “Spell Card”! Use the abilities of each character to kick the enemy’s ass!
In addition to the story mode, the game also supports online multiplayer play for up to six players. Let’s have fun by cooperating and competing with players from all over the world!
