i bought it on PS4 and i think i'm screwed, Sony has always been kinda shitty about doing refunds. Imma play the campaign today and if the digital uproar convinces Sony to give everyone a refund, i'll join in the mob and get my $80 back. I sorta feel like a guy who was just eating a baguette during the french revolution and got caught up in the mob. Sony does have a rep of only giving a refund ONCE per lifetime per account though, and I got a refund long ago on Driveclub.
If you bought it (digitally) on xbox microsoft.com is supposed to be pretty good about giving out refunds.
