About ERAIASON

✦ AI summary

ERAIASON lets you create and oversee a population of AI-driven robot creatures that evolve, learn, and adapt in a dynamic voxel sandbox as they struggle to survive and reproduce. Shape their evolution through environmental manipulation and genetic tweaking, or sit back and watch as their neural networks grow more complex and intelligent across generations in this unique blend of god game and evolutionary simulation.

EVOLVE YOUR OWN AI ROBOT!You are The (zoo)Keeper overseeing a population of evolving AI robots in a dynamic voxel landscape. These robotic animats walk, jump, eat, mate, fight, and adapt to their surroundings as they strive to survive and reproduce. In theory, the capacity for their intelligence is limitless, as their brains can evolve to any shape and complexity. Will you choose to passively observe their evolution, letting nature take its course? Or will you intervene, shaping their world and influencing their evolutionary path?Design your own animal robots, build custom terrains, manipulate the environment, interact with the animals, and watch as each generation learns, adapts, and competes in a simulated ecosystem that’s as unpredictable as nature itself. The fate of their evolution is in your hands.---------Introducing a new god game and evolutionary simulation, where you evolve the brains of artificial animals to make them more intelligent, to better achieve survival and reproduction. The animals are real AI robots running directly on your computer. They are controlled by classic neural networks and other types of AI such as non-axiomatic reasoning system. They have a simple form of vision sense, touch sensation, and internal sensations, and they can move each individual  body segment. They can eat, mate, and fight, all while learning and evolving in a sandbox voxel environment.Watch evolution passively, or enjoy various interactive features including:
  • Voxel World: place voxels and modify the environment with sand, stone, water, and more.
  • Impact Evolution using your Research Journal: modify mutation rates in your Research Journal -- higher rates means faster but more unstable evolution, lower rates means slower but more stable evolution.
  • Pick up animats: Pick up animats and move the animats around with left click.
  • Build your own Robot: Go to the Animat Creator from the main menu to create your own robot. You can save it and load it into a simulation to evolve its brain!

✦ AI summary

ERAIASON has an interesting core concept with its evolution system, but players find the execution disappointing due to minimal gameplay instructions, a limited environment, and an intrusive soundtrack that cannot be muted through in-game settings. The lack of environmental audio and poor optimization of the evolution mechanics make the experience feel incomplete, leaving players hopeful for future improvements rather than satisfied with the current state.

Not recommended Dec 28, 2025
So. I was enthusiastic going in. The sound track is awful and the only thing you can adjust in the settings is the language. No noise from the environment or NPC's just a really bad music sound track that you can't mute with in game settings. Besides that the game play and instructions are minimal and the environment you get to work with is lacking all around. Evolution system needs more optimization and better guides. Good idea, bad execution of said idea. Hopefully it gets worked on.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.
