I have to say I'm more than a little disappointed. I already feel like I've paid for a game that I'm not getting everything out of (becuase in order to fly the planes I want I have to go online to unlock them - which I don't have the time to do); now I'm being asked for £7.99 for a handful of extra content.
I appreciate that its a marketing decision and not a developers one, but I'd much rather have seen a patch correcting some of the errors seen by the community (and unlocking all the planes for all us offline players

) before they start asking for more money for more extras.
