I mean, perhaps I should also say a few words on why it matters that the game is released soon™ and not in a few decades when Ocean is ready at his pace as he seems to think the long journey doesn't matter and he'll get there in the end.
- Technology keeps progressing, and his game will look outdated in a few years if it still hasn't been completed by then. He would end up stuck in infinite rework loops if he wants to keep modernizing his game as there would be more content to rework every time.
- You don't know what the future holds, and the further in the future you're projecting, the more it is true. There could be war, there could be economic struggle... Patreon could shut down his pages (right?), maybe Steam next as a major offensive against porn games, and suddenly his full-time job working on his game could be jeopardized. How's he going to keep developing this game if he cannot pay his bills? Do it as a hobby during weekends? Considering how slowly he has made progress already as full-time...
- People will get tired of the wait and move on, which will further hurt his support and ability to continue. Are you as interested in your TV shows when you wait 2-3 years before the next season? I know my level of interest drops.
- He might also just end up burnt out or aspire at doing something else professionally in the future, and I wouldn't blame him for either, but that's why he should aim to have a manageable project.
These are simple reasons why any game studio at all never looks years in the future. This Patreon disaster was very predictable.
And no, his pace won't also magically get fixed by itself with "more efficient routine", longer hours or better hardware. These are marginal (albeit welcome) gains in the project scope.
