I never understood this....
"hey cool a game I like and I think it is worth 60 bucks thats why I am spending 60 bucks on it"
then
"what? a price drop It was never worth 60 bucks I feel like I am entitled to 10 bucks refund now. FU sony"
Seriously dont buy games full price so you dont need to complain about a price drop. I stopped buying full price when I was 12 years old or so.....
