I played the demo for Cairn a few weeks ago and I'm now really looking forward to it. The mystery meat protag with a british accent annoys the fuck out of me, but the gameplay itself is solid and I can see it being a real fucking challenge getting up that huge mountain, should be a comfy game for the winter time.
I'm also playing Jusant now since it was "free" this month, kinda the same concept as Cairn but a lot less mechanically demanding and in a very opposite setting. Its nice, but I haven't been eager to finish it, although I'm sure i will someday.
Most importantly, I've been playing Death Stranding 2 the last few weeks and I finally got to the big ass snowy mountain section i've been looking at in the distance this whole time. Setting up a zipline network to get from one settlement to go directly over the entire thing to the front door of the next place is so fucking satisfying.
