Oh wow a space expansion!
....yawn
Seriously? All the feedback provided by these forums and maybe 1% has anything to do with space....and this is what you guys have decided to waste time and resources on?
You want this game to live longer than a few months after this expansion(skyrim online debuts roughly same time frame) let me give you a hint. Get rid of the shoddy C++ code with the terrible garbage collection that causes half your problems. Do any of your developers know how to ~delete() ?.
Find a different business model. Free is great for content, but when you label it an "expansion" subscribers tend to want more from a game than a few extra features that will probably not keep them interested after an hour of gameplay.
The cat is out of the bag however and I wish you the best of luck with this. But I highly doubt you will generate enough new subscribers to balance the mass exodus of current subscribers in the wake of this "expansion". So for anyone here that feels the same as I do, I will probably see you in skyrim hobbling around with an arrow in your knee.
