I play games to escape my reality, not enter one like it.
Well the fact of the matter is that when games become realistic like this "teaser", it's still a game and can be programmed to however you like it. Would that not allow you to escape your reality and even shape it to however you like? To the point of it being comparable to The Matrix? If your reality is in a broken down building with military running through it, then I understand. Why are you so against a game that has 100% realism or even approaching that?
Sure, you can walk outside, but can you shoot people, commit vandalism and arson, go to different planets, have battles in space, etc. etc.? Yeah, no. There's consequences.
