I've become so comfortably platinumb
The reason GZ doesn't have Platinum Trophy in PS4 is due to SONY's regulation. They won't allow us to have them for non-full price game.
Though I've long outgrown achievements and trophies, this did actually discourage me from buying Resident Evil 4 HD on the PS3, as I thinly rationalized the platinum as an excuse to replay a game I've played over and over already. It also bothered me a bit after sinking infinite hours in Lumines: Electronic Symphony and not getting my virtual gold (platinum) star for doing all the things.
But hey, Metal Gear Solid 4 didn't even have trophies for the longest time. It certainly didn't stop people from getting that Big Boss emblem. This doesn't affect your console choice, does it?
