You're obviously not very bright and that's ok because we can never have too many ditch diggers but the fact that you think someone attempting to scam people would take the millions already made and use it to open up multiple studios which are staffed by hundreds of people who are actively creating a tangible product just makes you fucking obnoxious.
Given the scope of the game four years of development time really isn't that unusual, of course you probably know less about game development than you do how to spot a scam so your tantrum is no surprise.
I wouldn't start worrying about the state of the game until around the 6 year mark, especially considering how they are developing the game in pieces so their backers can better see how the development of the game is proceeding. This method, while great for transparency has a tendency to slow down overall development time.
It is called taking money for one thing and investing it into something else. All the while stringing investors along on something that might never and probably will never come to be. Insulting someone for showing lack of faith is uncalled for.
