to Docent Picolan: no need to make excuses...
Questions: how many people are on your testing team? Is the campaign playable at the moment (how many missions are there)?
What's uncultured about this? They didn't really tell us what they did and when they will do it!
The beta is needed to let users get acquainted with the game, not just to let them "play around"!
I'm telling you – if the add-on were fully playable at the moment, no one would simply delay the release.
