Yes, it's this argument again "Oh there shouldn't be freezing or overheating in caves blah blah". But on the last "Rhymes With Play" they mentioned that most players don't go into the caves, so it's worth bringing back up.
The reason that I personally don't go into the caves, is because it's so annoying to handle the caves with season effects. If you really want to explore the caves and have fun, you can only do it by wasting the good season of Autumn to do so (and nobody wants to do that). It's really annoying. If you want to explore them in Winter and Summer, you'll end up having to fill your inventory up with gear to survive caves AND gear to survive the temperatures of the seasons. Having to deal with constant sanity drop and lack of light, plus season effects is annoying. It's not challenging, it's just annoying.
There's this argument that players will just hide out in the caves through the entirety of the difficult season. First off, I don't think that's true. If a player has a base and decent gear, they will stay in the surface because sanity is a lot easier to handle. Second, I don't really see the big problem with players hiding in caves during the seasons anyway. Isn't that natural? Humans taking shelter from weather. Plus, I hate summer, I hate it because it's sooo boring. There's nothing to do and it's not really enjoyable to explore because a) random fires. b) constant overheating. I'd love it if you could go into the caves and just forget about all that.
Plus, I think its a great a solution for the problem of players joining a server in a middle of a season and not having any kit to survive. They can jump in the caves and done, problem solved. That's much preferable than having someone running around with a torch in Winter, burning everything in sight for warmth. And it will certainly get people going into the caves.
It just seems like such an obvious solution to me.
