I don't think so. I love my national native language, but it's terrible what this guys from Snowball doing with it in their games. The quality of translation is awful and they specially selling a game, which originally having one disc on two and more. (obviously to earn more profit) That is why I prefer English versions to others.
With Impulse, you download it, then you never need to connect to Impulse again EXCEPT: if you want to install it again. Otherwise, you can see what would happen. But that's good I think, because if I'm at school or something, and buy a new laptop, but left my CD god knows where, I can still install it. I bought my first SpaceDock game like 10 years ago (SpaceDock is now Impulse) then forgot about it till just a few months ago when I installed Impulse and vioala: there it was! With all the updates!
