Wall types I have made: Wood,
Core Wood logs stacked,
Core Wood pillars, like a row of tree logs,
Wood Beams, (purely for a wall),
Stone 3x3,
Stone Pillars,
Iron Wall,
Iron Support Beams,
Raised Ground
Black Marble cubes ...

I do see the Plains Camps Fuling weird huts, and that would be a COOL D L C to have, and maybe another D L C of Dvergr pieces you cant make yourself. I totally think people would do like a $1.99 or $2.99 for some more build pieces. I mean, I would have paid $10.00 for Mistlands, happily, too. Also, would pay $5.00 for a Dangerous / Odins Wrath version of the game, where they add mini bosses, and special items.
