I'm currently playing through it solo after getting bait'n'switched last weekend by the devs, and its kinda fun although too grindy in certain aspects, which clashes with the limited nature of its enviroments. For example, when it comes to combat-centric skills you will find yourself being able to level up the "blunt" and "sharp" weapon stats quite easily since you just gotta destroy furniture and cut up bodies for them to go up, on top of using such weapon types for day-to-day combat or hunting. On the other hand, raising the "aiming" skill, which governs how much you suck at ranged weapons, is a total pain in the ass since it only goes up by shooting at actual living targets which are limited and completely dependant on respawn timers. Another example is Crafting, which takes forever to raise, contrasting with agriculture, which mostly levels up by itself as soon as you start using it.
Overall I'd say the balance is all over the place right now (specially noticeable just after reaching the Manufacturing Sector for the first time) but I guess its fine since its early access. Pretty sure this is something the devs will go back to in the future. Worth a pirate if you want to try it.
