A game with choices as diverse as those I make in my own life seems extremely boring and useless. Not that I don't like my life, I love it. A game that would reproduce it would be redundant, wouldn't it ? I would like my actions in the game to have less consequences (so that I can have true freedom).
When you look at the video, even if this is not a scam, there are soooo many problems with this I don't even know where to start. To reproduce realistic scientific advancement would require players not to have the knowledge beforehand, which is not possible. Besides, if players become able to travel through space, it means the engine absolutely needs to simulate what happens at a level of precision that is simply not possible except if we build a quantum computer 50 times the size of the universe.
