It's available on PC and iOS as well, so if you've got an iPad or something that's an option. It's not particularly graphically intensive... I don't know if it'd run on my old macbook but if you've got a desktop it can't be too tough to run and it's available on steam... I think it's even on sale.
I live in new zealand, i have 2nd uk account, get my uk psn cards from playasia.com,, they are digital so as soon as u pay, you get your code shortly after. Btw AU NZ psn prices are a rip off , buy my games from ozgameshop as they are cheaper, and get my dlc from uk psn.
