Wow, the timeline is an horror story.

I don't understand the appeal of space opera games like this. They will mostly be empty zones of players.

I also have ideas to make an ambitious video game, with persistence and an open world. But I would rather start small and humble by releasing something that is playable, add cool features as the development progresses, but still providing basic features and playability at first, that would be slowly replaced by the more advanced features of the game. Making a game attractive quickly from the beginning is important, especially if you're using the crowdfunding model. Today it's possible to have a continuous evolution of a game, to constantly change and improve it.

The hardest will always be to track player locations in realtime, on a large world, while keeping the game smooth enough. Once that is done, the sky is the limit. I don't understand why so many games focus on the content (because that can be an real time and money sink), while the only things that are attractive for such games are the gameplay and the multiplayer.
