Doesn't seem obscenely hard. It actually reminds me very much of early day MMOs. After an hour spent wandering to find some place that was green instead of brown, I got ambushed in a settlement by a pack of raiders, broke a leg, got picked up by a farmer after the attack ended who started carrying me off to somewhere, before being ambushed by a couple of beasties himself. He fought hard but ultimately was brought down. The beast he was fighting bled out, I guess. I crawled to a bed and started the tedious process of healing.
Restarted, found a nearby town, started mining, picked up an NPC, kited a few packs of bandits in to the town guard, scavenged and now I'm well on my way to something.
Pretty cool so far. The atmosphere is growing on me. I like "learn as you do" progression that seems to get pretty detailed with the factors it considers.
Combat is hilariously savage when you're all so weak. Blood trails, hacked off limbs, people crawling around, playing dead, rendered unconscious. Respectable levels of detailed violence. No one is puking their guts out ala DF bu I suppose that's alright.
In a macro sense the environments are pretty empty, but when you sort of get down to the eye level of things they've got a surprising amount of variance and character and topography that makes them feel deeper. Maybe not the desert so much....but all the canyon areas and different biomes got enough going on to get me immersed and looking for the ideal place to build a base.
Seems like it will be quite a grind to get the resources together to start building a little fort.
