Honestly, the only things they could now do to fix this mess would be:
- refund the game purchase to everyone
- make the game free to play while working on fixing it
- go dark until they're ready to show Starfield gameplay (and it better blow everyone away).
Sadly, neither of that is very likely to happen.
It's very likely that they're going dark.
They haven't even issued a formal apology yet. Just a few half-hearted, insincere attempts to fix their problems. Which have created even more problems.
