During the Q&A part of the recent 14hr broadcast a person asked Yoshida if they could make it so that we could switch or even remove pillars and windows inside of houses. Yoshida replied with an answer of that part of the team had already been working on trying to make it so you can switch them out or even remove them. I love it when we ask questions like this only to find out the team has already been working on trying to make said request a possibility.
So hopefully they at least figure out a way for us to switch them out. As at least with a switch out you can then work them into a design better. Or have less pressure to have a house or apartment in a certain housing ward just so you don't have to eat up a slot in trying to hide a pillar style you don't enjoy. Which sure doesn't please the few who want 100% flat wall, but at least it would be something.
