What I can say right now I like the game very much.
Graphics: is great and the engine lets monsters and opponents off and spin off at too far though, but corpses are displayed realistically. For example, at a stone slope roll this or slip them down.
Story: Because I do not want spoilers, I can only say that. The story so far binds very specifically we know there is only "One" objective but there are many ways to go ^ .-. If someone like me has not played Risen 1 and 2 has Risen 3 still a very good place to start and you do quickly with the familiar story by collecting information by talking to NPCs.
Control: At first it was a bit strange (as I said have not played Risen 1 and 2 also know nciht whether the controller is the same.) But with the time to get super clear it.
I can only recommend the game so far, and hope that after the main quest can still explore the world and knock monsters can if they respawn. I see then.
