I started a new build in a 700-slot. I limited the space a lot by hiding/blocking off areas, and did some beautiful landscaping I'm really happy with.
Once I got to the relatively-smaller interior, I realized I was getting down to under 200 slots, then under 150. I know it's going to be a challenge with those last 100, playing the game of "ok, what to sacrifice, optimize...?" In the end I won't be able to do everything I'd like, even in a 700-slot area that's blocked out. Definitely can't do much creative cobbling, because every slot counts.
It actually started stressing me out, so I had to step away. I'll try stuff on PTS and get back to it eventually.
It's kind of nuts and disappointing, I didn't think I'd run into this in a 700; previously I only used 400 and smaller. I know some of you understand very well. I just wish we could get additional slots for existing homes.
