The Sims could use some more big city culture AND some more shell challenges. Take this tall shell and transform it into something magnificent! Normal shell challenge rules apply. Namely, don't add or remove exterior walls; you may add half walls, fences, spandrels, platforms; you may add interior walls; and finally, all wall heights MUST stay at the tallest setting. Can you make these skyscrapers into something totally different? #trymesyd #shellchallenge #shell #buildchallenge
