A space exploration video game. It had a famously bad launch, because the director had over-promised on basically every single feature. It was massively anticipated because the director had hyped it up so much. And when it launched, players quickly discovered that many of the promised features were only half finished, or were missing entirely. The backlash was swift, but the company said they planned to keep working on the game.

And now many years later, the game is actually fairly solid, and basically meets the original promises. But at launch, it definitely didn’t.
