@Stroom Here is the answer I received:
as stated multiple times already this is won´t possible. I´ll give you the main reasons:
The technical base of PlayCatan is old (for Software standards ancient). If there are any changes made to Java, the Browser architecture or something else, the program will simply stop working
We are not the owners of PlayCatan we are only maintaining it in its current state. None of the PlayCatan users do have contracts with us. Therefore we can´t simply start up a billing process again or alter anything on the platform that goes beyond maintaining its accessibility at this point in time
The EU decided upon a new Data Protection Regulation (GDPR) that will come into effect late May 2018. This means we would have to restructure the way all user related data is handled on PlayCatan. This investment alone surpasses every estimation on how many players are in fact willing to pay for using the platform (Despite the fact I mentioned above that we do not own it or any rights to alter anything on the platform as it is right now).
I hope this 3 points help you understand our decision as it stands right now.
