Well folks its here at last...6 characters who want to hide themselves in Russian tin can tubes for 520 days with not much to do but look at each other. There are NO windows in the 'cans', if there were simulated star fly-bys-[AKA Star Trek windows we all have seen on TV] would bring a sense of realism with star movement granting some 3D depth out a few well placed windows I can then understand that they may last 520 days...but no visuals at all is too severe to understand anything to gain psychologically. After all we do use our eyes.
OK folks lets have some fun with this one.
180 to 200 days is my bet for them to last.
Any other comments are very welcomed.
