We’re currently using the Severe Weather mod that does this (and some other stuff)

We used it too for couple of years until last month. It’s a very nice and very needed mod but it also comes with visual overhaul, which is wonderful but also buggy. There are problems with things not loading when client logs into game and sometimes it’s hard to notice that the weather/light is bugged and it causes eye strain. The author refuses to split the mod and to leave only weather in Severe Weather he also said that fixing the visual bugs requires the mod to be remade from scratch which he is not willing to do. I can uderstand that, everyone get’s bored at some stage and leaves for other games. I wouldn’t have bothered with fixing my mod if I left Conan for another game.

I’d love an Age of Survival where the game got back to that core theme a bit.

Yes Age of Survival, where weather is remade and takes humidity into account (you jumped into the river up in the snowy north and now your outfit is soaked wet? You are in trouble…)
Remade clothes and heat sources (when I saw in Valheim that my toon is suffocating because I started a fireplace inside my house and the smoke was accumulating inside I was blown away… I want that in Conan).

Not to mention I would like to see the fauna finally fixed, swimming crocodiles, spiders able to climb the walls and ceilings, venom stings/bites being actually dangerous etc etc… more types of flying enemies…

I think it is not that hard to do, there are mods, that just does this.

For Funcom probably it’s 30 minutes to adjust all the weather settings.

I was looking to do it myself, but I have very limited time to learn the devkit or to work in it. Also game updates change things or just break mods. And them mod need to be updated. With my limited time it would take me days to fix a mod, and broken servers cant wait days.
Also you can’t edit what Funcom had placed in the game but you have to put things on top of it instead, so you finish up with two weather systems you have to keep track of.

It’s easy for PC players to add mods. It’s impossible for consoles players.

Mods break, modders stop playing, and basic things like this should be in the vanilla game. I agree.
