There's been many solid games that have come through early access, and many games that have become really big hits because of it.
Things like Thronefall, Vampire Survivors, Ratopia. It's very interesting to see.
But there's also been many many more games that have failed, be it a lack of skill by the developers, community abandonment, a lack of interest, or having a ex-Blizzard employee with a ferret fetish involved.
Early access is somewhat of a risk, but... let's be honest, so is buying any game.
Look at Moonbreaker. Entered early access in 2022, being done by the Subnautica devs, 1000+ positive reviews, left early access in February 2024 to 255 players.
It's currently at 3.
