I would say that you should get them one day once they are either cheap enough or you really want them. Just remember that you will die in the Souls games, maybe even a lot of times which happens to a lot of new players. There are some Persona games on PS3. Persona 3 FES and Persona 4 are on PSN Store as PS2 Classics, but last time I remember they were only available for the North America PSN store, but that could've have changed. If they are not, the upcoming Persona 5 will be on PS3. If you're gonna start with an Elder Scrolls games, I recommend either Oblivion or Skyrim, however Oblivion has some stuttering problems and it may force you to download and install a few mods to help reduce the stuttering.
I don't rewatch a lot of things either. I have to really like something in order to rewatch it. If it is just something I find plain or not very entertaining, I just won't rewatch any of it.
