If only they revived some of those dead RPG IPs.

You know what, fine. I'll download and play Legend of Dragoon. 

This list just makes me realize how many IPs Sony abadoned. Some of my favorites too

Almost sure they do, were exclusives right?

Then realize how much better Wild Arms is.

4 pages and no mention of Rogue Galaxy not being in the OP. Disappointed.

As for IP's, I hope Sony doesn't go back to LoD.

I liked it but full of issues like most Level 5 RPGs.

you need to take a closer look at your genres I would argue that Horizon is a 3rd person action game not an rpg, also if you are to affix series do it for all game series you also have no puzzle section for games like, IQ  - intelligence cube Kula world oh no more lemmings - 3d Lemmings etc 

some more games my apologies if you already have some of them. 

destruction derby series -rapid racer - roll cage -  overboard - krazy ivan - extermination - roscoe mcqueen - steel reign - blasto - ODT "or die trying" - legend of legaia series - life force tenka - Assault Rigs - C12 final resistance 

I would have include Porsche Challenge but like formula one it uses a licence and that clouds the OP because Sony owned IP is different from Sony exclusive games otherwise we could include co published games whose IP are 3rd party owned or others  just exclusive to the platform.

So wht are you going to do with the formula one games listed seeing Sony doesn't own the IP?

 it's harder than it looks and not a straightforward task your doing great so congratulations
