Just bought this for the PS4 and I'm impressed with how it runs overall. I had hopes of a longer draw distance but maybe with some more polishing down the road, it'll achieve that.
Suppose I'm fortunate that I don't have the long loading bug but the pc version can take a solid 5 minutes on first run too. I do get the random hitches every so often, though. It can be annoying but they'll work it out, the pc version had that issue once before.
I've already sunk over 300 hours into the pc version so this is me, more or less, supporting the developers. I hope it takes off for them and doesn't get too roughed up because it's an alpha game. (Even for being in alpha, there is a TON of content and can definitely provide more than $30 worth of entertainment, supposing you're into rather unforgiving survival building games)
