Well, I doubt that anyone wouldn't have honoured those preorders - I'm pretty sure it would've never come to courtI believe they were even teetering on illegality at least in the UK if they weren't going to honor existing preorders.
... and not only because I'm sure Steam would have offered a full refund (I mean, they already have to do this for any game, for any reason), nor because they [the game designers] would've straight away been taken to court/forced to give back the money [thus they are actually losing sales this way], but also due to the fact that it'd look really bad on them to do so.
What I could've seen them doing, which I'm glad they didn't, was to not offer updates on the steam platform - or to offer keys to the customers [who had preordered the game] to download Metro on the Epic game store (thus forcing them to either cancel their order, or create accounts for the other software).
The fact they didn't do either of those kinda speaks well for them - but it's a very small 'kinda'


. It would take a special kind of indie developer to do something like that again, I guess. Too bad almost all indie MMOs have too many shortcomings elsewhere for it to even matter. But it would be cool to see something more cutthroat and not set up as every single nobody playing the game being the hero, it's so fucking boring.
