I too like physical, but if i run into game that may take a long or indefinite time to find , I buy it digital then get the physical down the line.
Yeah I've done that with a few games actually... and if the game is good enough I don't mind doing so either, just as long as I end up with a physical copy by the end, lol.
Buy it digital. The file size is only 10 gigs and its one of the best games of all time. No hyperbole.
But is it REALLY? :P
If I see it cheap on PSN I might consider buying it digital I guess... we'll see.
