Dude, you realise loads of game developers break these kind of promises all the time? Good example was the Panzer V/IV on WoT console edition... Oh man the fallout from that... But people kept playing. And unlike the Cobra... That bloody tank really was OP with twice the HP of same tier tanks, as well as twice the armour and weight.
The amount of games I play where something is sold "Once only and never again"... Only to be sold again a few months later... Hell ESO just did it a month or so ago with a skin.
I keep telling people this. FD is not special. If you think you own the exclusive rights to use the ship and FD can't retract this... Mate. You need to play a lot more games. I can tell you right now that there is definitely no legal barrier to it becoming available. It's all faith.
I didn't make the the terms of sale and I don't use the ship, even though I do have access to it. You might think of it as a good small ship, but I think of it as a crap medium ship in all but name. Maybe if there is ever a place only small ships can land implemented it might actually be useful beyond novelty and personal preference. I like to use small ships for their actual advantages, not as a poor man's Python or whatever.
I don't know about you, but where I come from asking or expecting someone to break their word or promise, that they specifically set the terms of in the first place while not under some kind of duress or something, is rather disrespectful.
To be clear, I don't like exclusives in video games, and I'd prefer if everyone had access to the Cobra Mk IV, but I respect Frontier's right to offer and maintain exclusive content and respect the rights of people who bought exclusive content.
You might as well have asked me what I would do if Frontier sells more exclusive content for all it matters.
For me it's somewhat of a negative that Frontier made exclusive content in the first place, but breaking the specific terms of sale of that exclusive content that are done deals now would be doubly negative regarding my confidence in Frontier's ability to run an honest, competent business, casting a shadow of doubt on future purchases I might or might not make with them. That's all; I've already bought into the game.
That being said, I do think people who pre-ordered Horizons and owned the base game would
technically be entitled to compensation if Frontier broke their terms of sale – the legality of it though is probably somewhat more of a grey area, since I think Frontier termed it as being a gift of sorts, even though it was specifically highlighted, listed, and further clarified as an exclusive
"forever" item being sold that players had to buy within a certain time-frame. A gift you have to buy something to get is not really gift in my opinion. I'm not a lawyer though and related laws and precedents for these sort of things vary somewhat between countries.
