That interview somehow just made me even more interested in the game, if that's possible. Murray actually addressed some of the doubts we've been having and at least absolutely clarified them, like the distance between planets and even more important, that creatures will indeed be more alien than just types of fish for underwater environments, or just quadrupeds etc. That's something I've been worried about but it seems they've really thought certain things through. Those cave and plateau formations looked very refreshing, something you don't really see much even in well handcrafted environments.
I'm just happy to have Space Engine in game form and actually walking on the surface of planets, and this looks like it's actually going to be an interesting game to play as well, so I'm ecstatic.
