For the first time in a great while the Landmark forum has been updated with a developer post that details the next significant update to the game. Among many other things, the new players will have a slightly easier introduction to the game.
Here's a list of a few of the changes:
New players will automatically have a plot set aside on Pioneer Island and they will begin in that exact spot.
Claim sites are increasing in size to 525 x 525 x 450 voxels.
Adventures & recources will now be designated only as surface or underground rather than as they currently are over 5 different layers.
Chaos Caverns will become "more fun" and give the player explorations, discoveries and dangerous activities to participate in.
You can read the full update notes on the Landmark forum.
