And how many of those startup fails ? Like 3/4 of them if i am not wrong. No , the office may be a mandatory thing to motivate the team and work together , sure each of them could slack at home individually then you end up with nothing getting produced at all .
So according to your analysis offices are 'mandatory' for successful startups? Hmmm, guess the likes of Google, MSoft, Apple, Facebook et al were founded in spacious state of the art offices. Lucky guys.
Reading your analysis it seems amazing that games get made at all. Or that small developers were ever founded and then developed into larger companies.
Or maybe, just maybe, they were like other entrepreneurs and skimped and cut corners when starting out, hardly paid themselves anything, did without expensive offices, got people to contribute without a salary in exchange for future equity. But believed in what they were doing and ultimately made a success of it in the long run.
And now kickstarter comes along and makes the whole process a lot easier, contributing extra investment with only a few promises in return. And all you can do is criticise the fact that it doesn't cover the entire cost of the project, willfully ignoring the future revenues the project will generate.
