"I hope we've gotten that across!" says Murray. "The idea, with the gameplay that we showed, is that the planets are dangerous. It hurts me that some people think we're making this ambient indie game that you walk around and look at trees and scan them, like some universal Pokemon Snap. What we're making has core action. I hope we got that across. When you're on a planet, there are creatures that are dangerous. You see the drones and they're just a sneak peak of the mechanical, and you can interact with - they can be dangerous and they can be friendly. You are really interacting in this universe."
Just thought this would be interesting to some here, as I've seen some skeptical posters question what the hell you actually do in the game. Personally, this has me excited.
