I was under the impression that Paypal requires you to have some kind of credit/debit card listed…?
Anyway, it’s not that’d it “invite” piracy. It’s that piracy would be possible, here:
That’s one file (of several) that makes choice of the vampire work on this site.
I could - I won’t - but I could copy every single file to do with it onto my desktop and play it for free whenever I feel like it.
NOW that isn’t a problem, because COV is free anyway, but you can see why they can’t put full paid games on a site. There’s no way to restrict access to a file without declaring it unreadable (which would prevent the game from working) afaik. Nothing easy to implement anyway.
You’ll notice - if you do some digging - that the “demos” aren’t merely coded to be shorter, unless you buy them. They actually only physically upload the files that govern the demo, for the exact same reason.
Again when you play via google chrome, or the app stores there is no easy way to access the code because it has been compiled into the device’s native package, .apk for android e.g.
So piracy is LESS likely.
