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.
Beam.NG is a rare one that been in early access since 2013 and has continually put out updates the entire time. It’s a completely different game than where it started with hundreds of new features and dozens of new cars. One of the greats imo.
Similarly, Factorio was basically a full game for over a year before the v1.0.0 launch, but the devs didn’t feel like it was finished enough to actually launch. People had literal tens of thousands of hours on it before it even hit launch day.
