I'd like to pick up some PlayStation games that I missed, but I'm slightly confused as to all the intricacies of backwards compatibility between the generations.
I know PS1 games will play on a PS2, so I don't need a PS1.
PS2 games will play on certain PS3s - but those command a hefty price premium?
PS4s will play PS1 games (from disk? do you have to repurchase them?) - will they play PS2 or PS3 titles?
So at a minimum, I need a backwards compatibile PS3 and a PS4 to access the full library, but it may be more cost effective to get a PS2 and a non-compat PS3? Is my knowledge out of date?
I have a Trinitron in the basement so I can hook up a PS2 there if need be, but I'd like the keep the number of systems to a minimum.
