My answer to inspiration is: YES! All of it. I'm up for trying nearly everything, but I guess my inclination is stick to the real world and smaller more intimate builds than larger, epic ones. Though probably a bit idealized as messy tends to be actually much harder to pull off.
Currently, I'm still working on the Safari Lodge/Camp; a tropical South Pacific Island; my own Home USA (just started and surprisingly giving me a lot of trouble getting the split levels to work out. Meters to feet is a big issue to the decimally challenged.) My Medieval tavern and village has sorta fallen into limbo. And in the previous version notably I built Wollaton Hall in Nottingham, UK. I've thought about trying to recreate it in Unity version, but it's only an idle thought. (I'm more likely to attempt it in Planet Zoo.)
I'm trying to stay motivated to play RW, but sadly, I am bored.
