I would want knitting as a hobby and ways for sims to be creative. I'm not completely sold on this yet. Some things are really not my taste but it seems like there will be some elements that I will like.
I do want the actual knitting though. I wouldn't just sit there watching one sim knit all the time. It would be something that one could do that I might watch for a bit and then come back to, then I'd enjoy having different results. I hope there would be interactions between family members during the knitting such as cats and toddlers playing with yarn. I mean, it's not necessary but what actually is?
I'm generally on board with having more hobbies for various sims. I'm also fine with some of those being ways of keeping a sim occupied while I focus more on others. It's one reason that I wanted the lounge chairs that we got. Unless you turn off all autonomy, they aren't going to just stay seated without something to do. I guess I'd rather have them knitting than running off for glasses of water or trolling teh forums.
To be clear, I actually want hobbies for sims not to just avoid switching autonomy off, but when playing a bunch of sims, I'd rather that ones I'm not focusing on are occupying themselves in some way. While I'd prefer more arts and crafts, I have some interest in this.
