I too would like to see the tree creatures as an add on for an additional pledge rather than as an SG.
SGs I would like to see:
the wall, gate and parapets from the Tested video with Adam savage
damaged/ruined versions of the above
scatter terrain and animals modular from the oxen and pig pen SGs
occupation type attachments for the small ground floor. something like a sharpening wheel, forge and anvil on a base that con be interlocked with the base of the small ground floor for a blacksmith. targets bows and arrows for a fletcher… apothecary
I second the idea of a market square mentioned on the KS
