I'm amazed at how apologist people are the moment "Double Fine" appears on the cover, it's an unknown company or something like Activision and people would be screaming bloody murder. Thing is, ok, the backers are all ok with this, so it's all fine and dandy, the problem is that the game NEEDS early access to do the second part, that means it has to be sold to people that initially never backed, and as such has to be new buyers. The scary part is when you remember that pretty much all of Double fine's games have been financial disasters (reason why almost no publisher works with them anymore, over budgeted mess that sells poorly is not the best of financial plans, looking at you brutal legend), which means that maybe not that many people will actually buy the game outside of all the backers. I mean, the game got a ton of money, but I highly doubt there is that much interest outside of the double fine fans and the old adventure game guard, it's very hard to revive a genre after all.
Also, yes, the game looks beautiful right now, but god forbid it doesn't live up because some bad PR can kill part two of the project pretty quick, I mean, I barely am getting any impression of gameplay out of the trailers and times have changed quite a bit from what was acceptable 15 years ago. Yes, double fine games are famous for being all quirky and I don't doubt that charm won't be there, but there are also known for having very debatable playability, be it shoddy platforming in psyconauts and a lot of annoying mechanics in brutal legend. The ideas are strong, but the executions sometimes suffers, though they are supposed to be old adventure game veterans.
Also, I doubt very much Tim Schaffer has any sort of ill will, he just sucks at planning, that doesn't mean people should be all "aw, it's fine cause he's so charming and artsy!", no, he should be chastised for fucking up with that, I assume he will make due the best as he can (reason why he did the whole early access dance after all) and if the project hopefully pulls through he will hopefully learn something and happy ending for all and if not, well, he'll have to dedicate some resources from other projects to finish it or let it die, with both of those options being less than stellar.
Also, call me crazy, but it's better to have a full game than have half a game that may not be finished, just saying and over ambition is the fastest way to go bankrupt, reason why there has to be a balance between ambition and resources.
