Its the exact same game, so it just depends on if you wanna experience it again.  Or if you wanna expand your okami collection for laughs

Same game, same trophy list. Can use touch pad though and the PS2 loading screen Mini games are back, that's it I think

I've completed Okami a total of three times(PS2, PS3 digital and PS3 JAP-copy(has English subs) .)

Is there any reason for me to buy the PS4 version of the game?
I can get a physical copy for about 20 bucks.

Is there any reason to buy the PS4 HD version when I already have the PS3 version.
