You inspired me to look into procedural object creation for my games.
I think its a good suggestion for StuffGen to have build in.
First step: Choose "body" --> Biological/Machine
Second step: Select transport type --> None/Flight/Drive/Walk/Swim
Third step: Procedural generation
Add random amount
Limbs attachments None/Flight/Drive/Walk/Swim
I would be so curious to what StuffGen's Procedural object generation could come up with.
And it fits in with the name "Stuff" "Gen" perfectly.
