YES! 100% support for this idea! I came to the forums specifically hoping to find a thread about this. Circus and aerial arts would fit so perfectly into The Sims 4's chaotic, expressive tone!
To add to this, here are a few specific mechanics and objects that would make this an dream pack:
Dedicated Aerial Disciplines: An Aerial Arts skill featuring aerial silks, hoops (Lyra), and trapeze. Low skill levels should feature hilarious, awkward fails, while maxing the skill unlocks breathtaking drops and synchronized routines!
Partner Acrobatics: The ability to perform 2-Sim and 3-Sim human pyramids or duo lifts. Having success depend on both skill level and the relationship/trust level between the Sims would add amazing gameplay depth.
Interactive Show Management: A new Big Top / Arena venue type. Players could build a custom show program (e.g., opening act: clowns, middle: duo silks, finale: trapeze), manage stage lighting/music, and see the audience's satisfaction meter react in real time.
Classic Circus Skills: Juggling (progressing from simple balls to flaming torches or chainsaws) and a dedicated Clowning tree with balloon sculpting, pie-throwing, and water-squirting flowers.
Must-Have Objects: Indoor/outdoor aerial rigs, backstage vanity mirrors with stage makeup, and a functional Human Cannonball!
SimGurus, please consider bringing circus arts to the game! The animations, aesthetics, and performance gameplay would be incredible. 🎪✨
