I was thinking here why don't you publish updates very raw, no matter how, updates would come out more often and people would be able to find bugs and you wouldn't have to do it, and each update comes out for longer and longer due to the increase in updates themselves, personally I would be satisfied that updates would come out in unfinished pieces and with bugs, but much more often, and I think it will be easier because you will need to monitor bugs less, let the players test themselves, especially on this playground you will be judged for bugs
It's more of a personal thing. I have a list of things that I want to do and I've crossed off alot of it already. For me I would rather put out all the things that I want to in one lump sum rather than split it up over multiple smaller updates. As for the bug testing part, I do have people helping me behind the scenes already with that aspect. With future games I plan on doing smaller more consistent updates. But I set out with a specific goal for this update to be the last major one, and I plan to stick to that.
