Is anybody else finding that they appreciate fireplaces more with Seasons?

Yes, indeed! I almost never bothered putting fireplaces unless they were in the more lavish homes, but now I find I'm placing even the cheapest fireplaces in most of my sims' homes! This is only because I will never stoop to paying for the thermostat bills since they're going to be RIDICULOUSLY high (apartments are exempt from paying the extra haha).

Very much so. I didn't ever bother with them before unless they were part of a downloaded or maxis made lot.
It's very cozy and with the ice on the windows or hearing the wind outside it gives the feeling of warmth to me as a player. Fireplaces are very immersive to me now. Most of my sims don't even get a thermostat for their home. The firepits .. while not as comfortable (always get the more expensive one if you want less fires) also make sense to me now.

Yes, I enjoyed including a fireplace in my builds and always turned them on to just make believe it was cold out. With seasons though, my sims now have reason to turn it on. There’s something peaceful about having one on.

Yes, I like that my sims will autonomously turn the fireplace on when cold. That's never happened before. But of course, now more fires are prone to start (my sim caught on fire when she turned her fireplace on). But that adds excitement to the game :)

I've always liked them, to be honest. Especially with the automatic lighting upgrade. But it's nice to see them with purpose now.

Absolutely! The upgrade makes it better.

Fireplaces are great, and I've used them even before. :)

I really want to do this, but I'm worried about them catching fire so I'm waiting until my sims have a high enough handiness level so as to upgrade them to prevent fires.

I still don't use them super often, but I am glad that they have a real use now.

I don't have seasons but my sims still get the cozy fire buff. I only use them if they are upgraded though. Hoping to avoid an accidental fire.
