I have a few alarm bells ringing here- One a sequel to the most expensive game of its era that cost somewhere between 50-70 million dollars back in 2000, is expecting to made for $2 million, something doesn't add up- A proper shenmue sequel can't be a continuation of what was before, they were amazing and groundbreaking in their day, but are severely dated now, keep that structure and you've failed before you start.
Secondly, the digital only release on PS4 suggests that it may be a Network title, which means a significantly reduced budget to not be a boxed title (Theoretically its a major triple A title, why no boxed release?) Also, Sega still have the Shenmue trademark as far as I'm aware, because they renewed it in 2014- So I'm assuming this is being made under licence from Sega, despite them having no involvement in the development (That won't be cheap)
Financially, there's something else going on here, and I'm not sure what it is, but I'm loathed to place money on the kickstarter until its more transparent what the game will actually be and where it's going (If it was a Sony Exclusive, I'd assuming they were subbing it, but with it coming to pc I'm not so sure)
