It's the ones who buy from Steam fully knowing they can't get a refund at all that get me. Then they spam going I WANT A REFUND as loud as they can as if they weren't aware of this very possibilty and bought the game anyway.
I would agree, but there's a couple of things you're forgetting. When I buy a game I expect it to at least be functional, I didn't buy X Rebirth from Greenlight, as a kickstarter or as an in development game like Prison Architect or Kerbal (both of which I own) I bought it as it was advertised - a triple A title coming from a games house with a long history of solid games in this franchise, each with small bugs on release but all of them patched and the game solidly developed over the years by Egosoft and the community.
What I got was a **** poor half baked port, with game breaking bugs from day one which clearly had almost no QA carried out on it. The first game breaking but was just 20 minutes into the game - which results in the saved game having to be edited, the fix coming from a customer. They purposely kept final versions away from review sites whilst advertising a fantastic looking game, in other words promised a solid game, delivered a pile of ****.
I've had a bit of fun in X Rebirth, but it's so far been out weighed by the enormous number of bugs and poor development work that sticks out like a sore thumb. No refund? I really don't care any more, I'll chock this up to stupidly in pre-ordering and simply never do it again. I should have learnt this after Assassins Creed III but that's another story!
Check my earlier post, I'm not expect a refund, but I am expecting Steam to think twice about sticking another Egosoft game on their catalogue. I've played the X series since 1999 and as far as I'm concerned this has all but killed it, which is a tremendous shame. I'm convinced this can't be resolved with bug fixes, it's bigger than that -the game is fundamentally flawed with poor interfacing, lack of essential features which I can't see any way to retro-fit into the game (Radar anyone?) and absolutely dire AI. I don't mind that you can only pilot one game, what I do care about is the rather pathetically stupid use of "Space highways" I mean seriously, does look like it's made for a D-pad doesn't it?
The AI though, you're in a fight? Just fly past them, they
STOP TO TURN AROUND.

Are you near a station? don't worry they'll get stuck if you fly around a bit. It genuinely is comical!
