Hi everyone,
Just wanted to let you know that I wrote to Playstation support, asking if there was a way to get a refund. I don't think there is, but at least they might hear about the issue and do something about it if several people write to them. Xbox players should do the same. Both Sony and Microsoft are responsible for distributing a game that obviously did not have a proper debugging phase.
I will keep you informed if there is any answer from Sony.
