Son'y lack of appreciation for its back catalog is what keeps me on Xbox. Maybe the first party games are not as good but I can access my past purchases going back to 2003 and I like to play those titles!

The PS5 is clearly able to play native PS1/PSP titles and yet Sony don't want to let us have access to our old purchases. Thankfully those titles can be 'backed up' and played on pretty much any Android phone.
