Hi guys do you think it safe to buy digital only games? I like Physical Copy also but the Price here in our country it doesn't change even it takes years the price still the same, because like PSP before I have a lot of Downloaded ISO games, and till this day I still have all those ISO download game on my back up, and if i have the back up of the games on my PC and for example sony will eventually close down there PSN , can i still install it again with my back up even if the PSN is down for good?
