What are your ideas for group activities?

I think the difficulty is getting sims to act together as a group. Right now they can't even sit and have lunch together properly, or witness weddings. They could do things like running, or swim racing but they wouldn't really be a group activity.

Absolutely. TS4's game engine seems to have difficulties dealing with this kind of AI simulation. Cause, effect, reactions etc. tend to generate simulation lags, so depending on the group activity it can really only be very simple and not involve too many sims. The engine can't handle it.
As you mentioned, Non-contact, straight forward activities such as swimming or dancing, don't really cause any problem and are relatively easy to implement. TS4 struggles when sims have to (emotionally) react to something as a group, while they're participating in one or multiple activities.

Apologies OP, don't mean to go OT. Just mentioning why certain large group activities may be harder to accomplish than others. I'm done now. ;)
Looking forward to seeing other people's ideas!
