I do not agree. 6DoF means that you move independently from gravity, but it doesn't necessarily mean that everything else around you does as well
The game could still run fine, but being commercial and 10 years old, how is people supposed to get it?
The official website doesn't give buying options, google returns nothing and it isn't available even as a torrent.
WTF? probaly a good game, but a relevant one?
more, it means you can move in any direction at any time if you want, but right it is only possible with no gravity
does it simply mean no gravity? or more?
