It strikes me as though they created the tech that enables them to procedurally create all these worlds, and are now trying to build a game around it.
The numbers are amazing when you hear them - 18 trillion planets, for example - but this could also be its undoing - unless they find a way to 'package' them. The idea of a game where you can explore and name things is, in a sense, intriguing, but with that many planets it seems entirely possible that you could play it for days / weeks without ever visiting somewhere that someone else has been.
Is exploring in a vacuum really that interesting?
