building is fun in the sims because it is limited. most of the limitations make it fun. To Me. there are some cases where i wish there were more options. i wish you could build walls on the half tile, i wish walls were on either side of the grid instead of straight down the middle so you dont get clipping, i wish wood tones matched. i do wish walls had a color wheel, or at least matched each other.
the fact that there's only a handful of colors of each item, and that you only have 90 and 45 degree angles to work with when building walls, makes building fun. in my experience, when you as the player have complete and total free will over colors, size, placement, it's too overwhelming, and sometimes too difficult!
i think games with building that are inspired by the sims often over-correct the lack of options, and grant too many.
