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.
Which probably wouldn’t work well. All it would do is make the game “release” when the time is up no matter what making it harder to know if you are buying a complete product or not. It’s not like valve will go in and kick a game out if they don’t think it’s complete enough, or even be able to define that in a way that wouldn’t just be arbitrary…
Yes, pros and cons to both approaches. Most games release unfinished anyway these days or some just sit in early access for years and years,
