I mostly like A13 so far.
Actually I had written a short first impressions review but half of it was obsolete a few hours later by the first patch
So I'm just going to say that A13.1 is yet quite a lot better than 13 and 13.2 will have even more balancing and might be something we can play on a server.
Although some people complain it's too simplified with there just being raw meat and wood and not all the different versions I think it makes it more simple at the proper points while with the skills and how you need certain tools for different jobs adds more complexity at other more interesting ones.
Just right now still even with 13.1 I think early game is quite a challenge, especially for people completely new to the game.
For example you need hide for a forge but - without watching a tutorial or something - how am I supposed to know that your best early tool for that is the bone shiv? The first few days I had been hitting the corpses hoping for at least 1 hide with my axe wondering how I'm supposed to ever get a knife for this task without a forge.
Hitting zombies in the head is quite difficult now especially with crawlers thanks to the mo-cap and thus increased head movement. It seems like you don't hit even though it feels like you actually hit the head, it's a little frustrating. Even more so with how expensive arrows are the first week or two.
I just hope they never add "spoiling" to food like they have it in Ark or also The Lone Dark. I hate it so much.
It's already bad that, at least when your skill isn't good enough - you greatly decrease the quality of an item once you repair it. A mistake you only make once. A repair penalty is also something I hate in games...
So yeah. Not going to rant too much because all things might change again with A13.2
However. One last remark. Prior to A13.1, so with A13, the moaning of the female character when running and doing any kind of activity was absurd
they changed and improved that greatly however, thankfully.
