Point of thermostat?

I like the thermostat and I like that now there are things that you have to spend money on unexpectedly whether it be high heat bills or replacing items after a storm. It was so easy before to accumulate and keep money and now there is finally an element of challenge to it. This pack is a giant breath of fresh air for the game. Rags to riches challenges are so much more fun because now there is actually an element of challenge to them. So are legacy challenges because of the risk weather has brought your Sims are no longer 100% guaranteed to survive to old age. I am loving it! The devs have is several opt out on the thermostat, put some regular clothes in the hot and cold categories they can change into in the house during extreme temps, buy a reward trait that makes them nonreactive to temperature, and specifically for winter put fireplaces in several rooms, or save up for a pool to use in summer.
