About
Add to Wishlist, Dominate Empire Gensokyo!
This is a relaxing, casual Touhou Project × 4X Strategy game (like The Battle of Polytopia and Civilization)
You will lead an empire and vie for dominance against the maidens of Gensokyo.
In this turn-based strategy game, you must explore the fog of war, expand your territory, build cities, raise armies, and conquer your enemies.
Face off against empires led by other Touhou characters—choose to ally with them or betray them. In the end, you must defeat all rivals to dominate Gensokyo.
Fast-Paced 4X Experience: Say goodbye to the tedious late-game grind! With compact 30-minute matches, you can enjoy thrilling strategic battles anytime, anywhere!
Rich Playable Factions: The launch version includes 4 distinct factions: the Scarlet Empire, Houraisan Empire, Moriya Empire, and Komeiji Empire. From "Pharaoh" Remilia to "Emperor" Kanako, each civilization features its own unique hero system, tech tree, and special units!
Online Multiplayer: Supports online multiplayer for up to 4 players! Face off against your friends, or test your strategies against other players in public lobbies!










#1 The Princess's Collection In the beginning, this game—TOHOTOPIA—was merely one of Princess Kaguya's many casual game collections.
#2 An Unexpected Hit! One day, on the "Eientei High-End Forum," a trivial argument between the Three Goddesses of Faith unexpectedly caused a butterfly effect. A series of coincidences fermented, and by a stroke of luck, this game went viral across Gensokyo.
#3 The Esports Tournament! As events escalated, TOHOTOPIA became the hottest video game in Gensokyo, leading to the grand opening of a fervent Esports Tournament.

(Experience the detailed story within the game!)
#4 Join the Fray! The girls formed teams to sign up for the tournament, drawing various "Great Leader" character cards to lead different majestic civilizations.
"Pharaoh" Remilia stands atop the Pyramid, gazing down upon her Crimson Dynasty.
"Emperor" Kaguya Houraisan stands proudly before the Arc de Triomphe, sword in hand, writing the legend of the strongest Grand Armée.
"Philosopher King" Toyosatomimi no Miko, wearing the Sassanid crescent crown, overlooks the lights of Ctesiphon.
"The Butcher" Zanmu Nippaku, clad in the purple robes of Constantinople, ascends the throne of Byzantium.
Sanae Kochiya, the Incarnate God, inherits the will of the Iron Chancellor, while the name of Hakurei is sung in the halls of Valhalla.
The wisdom of Krishna spreads within the unconscious, while the glory of the Demon Scrolls rises alongside the smoke of London's factories.
Thus, Gensokyo's unique and joyful "Age of Empires" begins!

I'd love to recommend this game but for now it's impossible for me to do so. The balancing of the factions is so bad it leaves me wondering if the dev actually has bias when balancing the empires. You got Scarlet that feels prehistoric and their heroes are just glorified existing units. And then you got Moriya that doesn't have a single hero that isn't stupidly OP, has the best economy, has exclusive access to the best unit in the game (arbiters), their giants are so OP you cannot even try to use water to gain an advantage through water tiles... And somehow Moriya keeps getting buffed! As of the latest patch they are now starting with a rider (best unit to scout) instead of a warrior! Moriya, Hourai, and Komeiji empires feel super toxic to play against. Hourai because of immortality stacking and their giants. And Komeiji because of fear stacking and how restricting Satori is. Kaguya should not be able to give any unit 9 stacks of immortality period! Satori should not be able to completely shut down heroes' abilities! If you want to play with friends, the game is alright; you'd probably need to agree to ban a couple of things to have a positive experience for everyone involved...

I've never played a civilization game in my life, this was my first time experiencing a game of this genre. My god, I have never had so much fun playing a game and feel so rewarded for my agency. This game hits all the right neurons. I would LOVE to have this game publicly showcased and have more attention garnered to it. I can only speak so much on the gameplay, as I have not played a civilization game before this one, but if this is any indication of the games, I may be inclined to try others. The factions in this game are very fun and gimmicky, and every faction has their ups and downs on how they want to be played (although the komeiji empire is a bit strong, I don't think too much needs to change. I think their gimmick is really healthy.) I do love multiplayer games, and I'm so glad this game has multiplayer support. More people should bring awareness to this game, it's got a bright future. I'd love to offer more, but I cannot think of anything at this current moment. Just buy this game. Try it out with your friends. It's fun.
这个价格我只能说纯纯的好游戏,即使不了解东方当Polytopia玩都没问题。 芙兰这么强的角色还能同时出四个,我说斯卡蕾特真王朝了。
好玩爱玩,就是朋友不玩,都在玩帝国三,快点开匹配或排位模式,不然早晚凉凉,东方圈子太少了,玩文明的嫌弃太简略,玩帝国的嫌弃没操作
