In Reus, you control powerful giants that help you shape the planet to your will. You can create mountains and oceans, forests and more. Enrich your planet with plants, minerals and animal life. There is only one thing on the planet that you do not control: mankind, with all their virtues and and all their vices. You can shape their world, but not their will. Provide for them and they may thrive. Give them too much, and their greed may gain the upper hand.
The Humble Bundle version is DRM free. So, there must be Humble bundle torrents out there, that are a legal way to get the game.
If there aren't any, PM me and I'll get the torrents up.
