If u care about bc that much then u should play on PC.giving bc priority over new games is backward thinking.
I would agree if the PS4 actually had a good library. It kind of sucks. I mean I read multiple threads on this site praising Shadow of Colossus, for example, when it was released on PS4. If the PS4's library is so good, then why are so many people praising Shadow of Colossus? Don't they have better games than this one that came out two generations ago? Guess not.
There are a lot of great PS2 and PS3 games that I don't want to buy again. If Sony expects me to buy them again on PS4, then I'll just sell the PS4 and play the older versions of the game.
