Even though Early Access can be an incredible thing to allow developers to build up their game with the community, and pull in some early funds, it can also go very wrong. And now Valve are making it a bit clearer for you if a game hasn't been updated.
Yes, I have over 500 hours myself and I am playing it right now aha.
I would recommend the game and it is worth the money. That doesn’t mean I am going to pretend it is perfect and without issues. I am constantly wrestling with things in game, crashing and running into bugs.
I am also way more critical of games I like, because I want them to be just that bit better.
