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.
