Don’t know why, but yes. Now, they are trying to fix that fiasco, with GMG support, but leaves bad taste.

Well… Yes, but actually no. I mean, they’ve revoked many, many keys. Some of them may be from scalpers / stolen credit cards / cheaper regions.

But… There is key selling store, Green Man Gaming. Publishers are deliverying keys to GMG, only them. Perfectly legal keys. And they still revoked that keys.

My suggestion for tinyBuild is, if you want to get rid of scalpers, just dont sell game outside of storefront. Like Steam/EGS/GOG. If you want extra cash from stores like GMG/Fanatical, live with it.
