I'm working on another build for Sims 4. And don't worry, I still plan to pop back in to Sims 3 to finish the two WIPs I've been sharing here.
Personally, (and off-topic) I prefer building in Sims 3 so much more. Seriously. Playing Sims 4 and building makes me miss Sims 3. Part of it is that I'm so used to Sims 3 but an equal part of that is that the devs behind Sims 4 limited a lot of the things I enjoyed... like using the cheat moveobjects... I've said it before, I know, but I just can't get over how a basic cheat such as that didn't migrate to the new game.
Anyway, I'll be getting back to you on my Sims 3 WIPs eventually. Here's a gothic Victorian I'm trying to build in Sims 4:
One of the frustrations I have with Sims 4 in regards to this build is the ability to not use the end wall coverings where I want them. Sims 4 auto-places the corner wall pieces with the brick accents. In Sims 3 I could choose where to place them and it looks much better, too.
Enough complaining though, I'm seriously trying to enjoy Sims 4, I promise. :)
