The guy who got the early copy was for PS4. He got to the center of the galaxy in 30 hours of game play. He saw about 45 worlds. All of them had some sort of life (small rodents or something) but he never found a "green" planet.

He wont say what happens when he got to the center though. Lots of speculation on what happened but the guy never confirmed it. Says he doesnt want to spoil it for people. But as more people get their hands on the ps4 version you can guarantee it will be spoiled.
