Support for High Gravity Planets
I exported a save game using the Alien Planet, then edited the world file to set Planetary Gravity to 1.9Gs (up from 1.1).
When I tried to go back into XBOX and load that world, it tried but gave an error. I don't recall the exact wording, but it made it sound as if the XBOX version could not support that setting. Which seemed odd. But even if that is the case, it would be nice if it would so we can make some more challenging environments.
