I should clarify that this is not a strategy game or god game. It more akin to a management game. Everything that takes place in the game is a result of the resources that you create. That is not a criticism of the game, I rather like the way all the elements fall together. Reus stays a very unique title even 3 years after its release. In Reus the player controls 4 titans which each have different abilities that interact with each other. The player uses the different abilities to create resources. If resources are available a village will settle near them. Players interact with villages by placing resources within a village's boundaries. Periodically each village will initiate a timed challenge based upon the resources currently available to the village. Completing these challenges give you an ambassador which unlocks more abilities from a titan during that playthrough. There are 5 biomes in the game: swamp, forest, desert, mountain, ocean, and wasteland. With the exception of wasteland each biome has a different set of resources that can exist there. Each resource can generally be upgraded about 3-5 times (you get a choice of two for each upgrade). These upgrades are usually branching so there are around 15-20 different upgrades per resource type per biome. As you can tell there is a huge amount of variety in this game. The main reason that I keep coming back to this game is probably how relaxing it is. That is not to say the game is easy though. The difficulty of the game lies in completing challenges (of which there is a long list) to unlock higher level upgrades for resources. It is very hard to lose in this game (it is possible though). But the higher level challenges are very difficult and will take careful planning to execute. The planning involved is mostly centered around space management and a deep understanding of the different synergies between higher level resources. If you want a relaxing title with strategic depth I highly highly recommend Reus.
