Or are you referring to Shadow Hearts being a pseudo-successor to Koudelka?
Yes, SH being the spiritual sequel to Koudelka - it wasn't quite a sequel but definitely had its roots in it.
I think it's fair to say that there's nothing pseudo or spiritual about Shadow Hearts. There's a direct link there.
As for Persona, that series had time to gain some notoriety in NA, because those were the only MegaTen games released during the PS1 era.
Resident Evil 4? Good controls, good graphics, hated the story and *loathed* the escort missions. My least favourite RE of all of them.
What I saw of FFX-2 (watched my friend play the first hour or so ..... and I fell asleep while he was playing it) was enough to convince me it wasn't the game for me.
