Reus is a latin word that means "guilty" or "culpable", and it's a curious name for the forthcoming god-game from independent studio Abbey Games. What are you guilty of? Perhaps we can take the word broadly to mean "responsible". This makes sense, because in Reus, you play as a omnipresent titan, responsible for the development of the earth and its civilizations alike. This preview video shows the titans digging lakes, pulling mountains out of the ground, fending off angry human armies and eventually meting out retribution for mortal arrogance.
Unlike most god games, in Reus you, the god, are visible on screen at all times. Why? Perhaps it's to emphasize your responsibility for the world you control. A god that takes responsibilty for its illogical actions? That would be a nice change.
