Game pageReus 2: let civilizations grow from nature’s combinations

Place plants and animals, connect their synergies, and watch human life flourish. Reus 2 finds its pleasure in small placement decisions that help a planet grow.
This is not a city-management game about laying out streets and homes. Reviews describe the appeal of combining natural elements into a placement puzzle that meets a goal.
What makes it fun
When symbioses pay off
Place plants, animals, and minerals with their synergies in mind. It is satisfying to see the extra yield meet a city’s needs.
Build nature around a city’s needs
Work back from the food, science, or other resources a city needs when choosing Biotica for its biomes. Humans use what you place to grow their city and pursue the era’s goals.
Draft choices reshape the plan
Choose from the Biotica offered in a draft with your existing ecosystem in mind. The choices you draw can make you rethink how to develop the planet.

A typical run
Command giants to shape terrain and develop ecosystems of plants, animals and minerals.
Settlement quests unlock biotica drafts. Choose an option that fits your existing layout.
Eras bring different goals. Challenger Quests are optional, so you can pursue their rewards or continue without completing them.
Finishing a planet can prompt another experiment with different giants and combinations. Reviewers find that newly unlocked elements give the next world a purpose.

Core systems
Symbioses
Meeting a bioticum’s conditions improves its yield.
Look at adjacency and biome conditions, not just standalone strength.
Micros
Place Micros from the Micro Shop using charges.
Some types cost more with repeated placement.

What sets it apart
This is more than quietly watching from above: reading conditions and changing placements changes the outcome. Calm scenery accompanies a substantial combination puzzle.
Learning curve and difficulty
Check biodiversity before adding more powerful biotica. The official explanation says varied biotica support biodiversity, which stronger biotica need.
Builds and playstyles
Start with a human ambition
The available later eras also depend on the state of your planet. Read human ambitions first, then shape nature around the civilization you want to support.
