Nerd rage know no bounds
It's nice to see that the nerd rage can span forums. I could offer that there is an offline version of the game at the moment ... it is the tutorials.
The problem is that the game client is exactly that, a client and the universe is running on an Amazon cloud service. Join the dots and you realise that they have not and probably will not be porting that Amazon service to something that runs on a client workstation.
