It seems very broad and very shallow, like an engine proof of concept more than an actual game... how is this the result of ten years of effort?? Mass Effect had three games in that timespan, The Old Republic reinvented itself and added space combat in less time, and so did Warframe...
I know that for the past 3 or 4 years they've basically rebuilt the backend in micro services on K8s, so that they can scale the game horizontally and add the really crazy persistence features they have planned. I think they founded a separate company just to create this new graph database to support the persistence features as well. I think a lot of the delays have come from that work and wanting a game like Mass Effect, but where 100's of people could be playing and interacting with each other concurrently.
I only found SC a couple years ago during the height of the pandemic. I just had a great time flying around in the giant space ships with my friends and I haven't spent much money on it, so it's hard for me to be too upset about the delays.
