As a species we are in a rush to destroy our planet, so in a couple of hundred years global warming should take care of everything. It is a shame it will take most of the animals with it, they didn't deserve this BS.
I am not saying it has to be high end hardware, though that would be nice as todays high end will be mid range by the time SC is released. While you can dumb down graphics to run on crappy GPU's, for the core engine you have to base it around the lowest hardware you will support, so if they design it to run on a crappy Celeron, then my i7 will going to waste and the game will be very limited in scope going forward. A lot of people are backing the game as it is a pure PC showcase.
I had never heard of that one, it actually looks a lot better than I expected! Not that I would want to play it now, but is fun for nostalgia.
I would be genuinely disappointed if SQ42 can play on a low end PC.
There is no chance current gen consoles will have the horsepower to run SQ42/SC. That may change with Scorpio, but I think there would be a nerd riot if the game is announced for consoles before the PC game is released.
That is a good question! I just tried an EVA in Mission ISS in VR (incredible!) but the only thing missing from the simulation is your suits hands so I couldn't see how real astro/cosmonauts do it today.
