I loved Martial Arts and Ballet in 3, my Sims' kids were always getting into something, lol. I didn't realize until seeing this post just how many options for hobbies and games we had in 2. Imagine if we received a new hobby with each release or patch, then everyone could have a feature they wanted... but wishful thinking never really gets anyone anywhere, imo. I picked body, though, because I feel it was the best of both if you had an active or fitness oriented sim and wanted some new animations but didn't want to simply work out all the time (IIRC, Martial Arts also raised the fitness skill). Crafting was a close second. My mom and I are pretty creative people, she used to watch me play sometimes, but we can't always accomplish what we set out to do for various reasons in RL, so that was the next best thing for us at least.
