I'm playing it a bit.
It feels a bit like Monster Hunter in that you need to get your head around certain concepts before getting into the real game and if you try that first, though the game does attempt to block progress before you get at least a few necessary items (but also gives you a way to ignore all that) I guess you'll get frustrated.
You have to first understand the backpacks, crafting items, cooking food, stamina/hunger/thirst systems, light sources, all that jazz. Once you figure it out it seems simple enough and you realize resources are quite plentiful to make survival itself easy (like always having clean water available in town, which you can take with you in waterskins and being able to sleep in town without the threat of enemies so you can spend all the hours repairing gear and stuff).
I think I missed how to make a campfire too, as I wanted to cook something but ended up doing it in a kitchen in town since I was close, I'll need to look it up.
It only gets more complicated when you factor in other elements like enemies you meet in the wilderness or when you want to plan for longer journeys, quests, or whatever may require you to do things like craft rations and not just simple food to have it last longer (different food spoils faster or slower). Combat isn't Dark Soulsy like it looks. there are slight similarities but this is a CRPG game first with mouse based controls and hotkeys for skills with cooldown timers. It feels more RPG and less pure action, though you'll still need to dance around enemies and attempt to avoid attacks manually. It's kind of like a modern Gothic game in that and in how you need to pay trainers to teach you weapon skills and improve your effectiveness in various aspects. And you do start shit.
The story's pretty silly in the beginning but I guess it mainly wants to give you the idea that you can do whatever the hell you want, just past the initial sections I'm given the choice with NPC dialogues to head down three wildly different paths, which I can ignore of course and just go do whatever.
I like it so far, it feels quite polished though there are some elements I didn't expect like the towns and other areas having loading screens rather than being a fully free open world. Technically the game seems fine other than not being able to maintain 60fps on my PC so I locked it to 30 and left it at that.
Still, it's too early for me to speak for the complaints some people list, they could become apparent later on. It's worth noting however that the more reviews the game gets on Steam the more positive the result seems to grow, it started negative (or borderline), then mixed and it just reached the mostly positive label. Some of the early complaints seem quite over the top, people talking about not being able to kill shit with some crappy club they crafted out of wood when you can find nicer stuff by exploring the starting town. Not to mention the game's not just about going on a killing spree anyway.
