Your thoughts on Rabbitholes?

If there's as many lots per world as there are in The Sims 3, then I'd be fine with it.

The Sims 3 having rabbit holes felt more practical. There was the open world, and always a great deal going on, and having Sims away in town using different buildings was good at times, and there was variety. Building skills, following up opportunities, raising needs, going on a date, there were lots of things to choose from. When I was playing with 6+ Sims, it sometimes helped to send one or two off to do those things when I wanted to focus on the others, or if things were hectic for whatever reason. Even with just one Sim, I liked looking around the area when they were using one of the rabbit holes for whatever reason, because it was fun to see what everyone else was up to in the open world in the meantime.

Career based rabbit holes have always been in the series and I've never complained too much about them as a result, but in 3 it was nice to actually see Sims go to the building they worked in, and there was the ambience and such, so it made things feel more varied. In 1 and 2, at least you get to see Sims coming home and leaving via carpools, busses or their cars and such. Sims vanishing into thin air in 4 just feels lazy, because it is. The vehicles in 1 might have been borderline static images, but at least Sims didn't just enter the ethereal void until aftey got into the car.

I think The Sims 3 ambitions had a good way of dealing with it. There wasn't a full, live doctor career, but it added live gameplay to what was otherwise a rabbit hole job, offering you opportunities to go out and interact with Sims by diagnosing or vaccinating them, and the chance for Sims whilst you were out and about to have bad turns your doctor could help with. There was an option to skip them with no penalty, but there were gains if you did them. It wasn't much, but it shook things up a bit.

I have no problem with them.

I avoid them as much as I can. I never play careers, only skills.

Career rabbit holes are fine with me. I prefer real stores like TS2, though.

I don't mind them at all. I actually prefer them to the playable careers. My Sims' jobs are just supposed to generate money, I don't need to play through their work day every day. :)

I don't mind them so much depending on the venue. I would like to see more open careers and even school but I wouldn't mind having a rabbithole venue to go to in the mean time. It beats just having our sims disappear in to the abyss when they leave the lot for work or school.

Edit: I would like for things like restaurants, supermarkets, etc. to be open venues though.

I don't mind rabbit holes for most things, but like grocery shopping, and clothes shopping, and libraries, I would rather have an actual lot.

I don't understand this argument either :)
I don't mind rabbitholes, they're certainly needed when managing multiple sims even without open world. I especially don't mind them when it's something like theather or game match because I understand how challenging it would be to make them believable otherwise but I like to have them anyway. I don't have much fun with bullet lists open works, though a fully fleshed out career that makes sense with the world and has unique interactions that are not just "click on this machine, drink coffee" is welcomed. I like firefighters, designers and nannies for example.
It may be intresting to entertain the idea of a game without rabbit holes. I guess sims would need to be really smart for it to be possible.
Edit: Wanted to add how I want rabbit holes to be improved. Given that they're Sims 3 style I'd love if I could build/decorate their exterior. It was the only thing that ever bothered me.

I am against rabbit holes because I feel that Maxis are adding them to the game instead of actually adding gameplay and content. I think that they could be used as an alternative if the player wants to send their sim off to a rabbit hole, like the way the active careers give you the option.

It has gone too far now, they add caves which are just rabbit holes where your sim is pretending to explore them instead of actually making caves that we can explore.

If you want to send off your sim to a rabbit hole while doing something else, fine, but they should not be used as a main gameplay feature for a game in 2020 which are making them billions, they are nothing more than your sim turning invisible and the game showing a text message.
