Same here,I cant play the non beta version for long, it seems almost like a diffirent game.
And the same here. Since the beta started I've only played 2.0 once and that was because my son wanted to play. I can't get motivated to play 2.0 even though I'm making no "progress" - there are just so many things in 2.1 that make the game better. Apart from Module Casino and a few odd UI design choices I really think 2.1 is the best content update so far (sure, 2.0 brought us planets so was the biggest technical addition but 2.1 brings more to the game itself).
And I also like the way FD are handling the beta. Based on the timings surrounding the Dangerous Games, it looks like the beta will be lasting another 2.5+ weeks at least so it looks like they are keen to address all significant bugs and sort out balance issues before live release. I personally hope they don't let any mission-related bugs slip through as it's such a core part of the game and if they did it would be a real shame especially after what happened with 2.0/1.5.
