I was in early access for Subnautica. It proves that for every controversial issue - microtransactions, DLC, early access - that is so often abused, it is possible for a company to do it right. Subnautica did early access right.
I won't be getting into this one, only because I'm looking forward to the full experience so much that I don't want to dilute that experience. Subnautica was one of the best games I've played in years, and I can't wait for the sequel.
