4. Always backward compatible

Star Wars KOTOR System Requirements. I can still play this on my Windows 8.1 machine

Ever tried to play a PS2 game on a PS4 or PS3? There is a problem with that as in you cannot. PS4 and PS3 are not backward compatible with PS2 games. It's a business tactic by console companies to make by their new console. With PC you will never have that problem older PC games will run on newer PCs. Even old DOS games will run on new PCs. You do not have to worry paying more money playing your old games again.

Sorry PS3 Owners no Backward Compatibility for you
