About this game

🏰 Legacy of Kings: Plague Era – Can you survive the Great Sickness? 🛡️
The once-mighty empire has fallen. A devastating pandemic has swept through the realm, leaving a toxic green contagion in its wake. This is no longer just a game of building—it is a battle against the Black Death.

In this idle tycoon, you are the last hope. Rebuild a kingdom from the ruins of a dark apocalypse. Clear the infestation from your lands, manage resources amidst the sickness, and restore life to a world choked by disease. Whether online or offline, your mission to cure the land continues.

💀 FIGHT THE EPIDEMIC, REBUILD THE REALM
The world map is hidden beneath a lethal plague haze. As a leader, you must venture into the green mist to reclaim your territory.

Purify the Land: Accept vital quests to clear the infection from tiles surrounding your cities. Watch the toxic clouds lift as you push back the contagion.

A Gritty Medieval World: Experience a haunting atmosphere filled with boarded-up houses, lonely graves, and the shadows of rats and crows circling ruined castles.

From Ruin to Royalty: Take over a dilapidated, abandoned castle and transform it into a fortified sanctuary against the outbreak.

🔹 WHY YOU’LL LOVE LEGACY OF KINGS
Strategic Survival: Rule over a medieval dominion ravaged by the plague and build a flourishing empire once more.

Automated Restoration: Your production thrives under your command—automate supply chains to fuel the fight against the infestation.

Explore the Wasteland: The vast world map is full of secrets—discover hidden splendors buried under years of sickness.

Idle Progress: Your influence expands even when you’re offline, making it the perfect strategy for survivors on the go.

No Pressure, Just Strategy: Delve into a realm where the only pressure is your own strategy to outsmart the Black Death.

Legacy of Kings isn't just about rebuilding—it's about surviving the plague. Enhance your strategy, manage your resources with finesse, and heal the world before the contagion takes it all.

Will you rise from the ashes, or fall to the infection?

At Level 10 so far so good, may update at Level 20 Level 20 edit: it could be worse, it's not the best game in its class but it's - for now - better than PostApoTycoon, the game of this type i played previously..technically still am but you know, rarely. However i am noticing a trend here. The higher in Level you get the more boring it becomes mostly because exploring takes forever and is only done by YOU! A building you place and slowly explore for you would be a amazing addition for 100 gems

PostApoTycoon is better, imho. This game is visually more appealing, but it is really, really grindy. I never feel like I'm gaining momentum. And the ads feel punitive. They pop up when you're in the middle of something, which makes me annoyed and unlikely to buy anything. PostApo, rewards you for watching ads. You never feel rewarded in this game. Am likely to ditch it, soon.

No forced ads. This is a pretty fun building and exploration idle game. The main draw back is that your income does not keep pace with escalating exploration costs, so now at level 23 I can only explore a few squares at a time, so I'll probably get tired if it soon. Otherwise it'd be 5 stars. Similarly, treasure does not scale with level, so now it costs many times the value of the treasure to actually get to it. Did not tire of it, glad I didn't, upgrades inproved my exploration rate.
