I like playing RPG too
Persona 3 is my favourite, i'm really excited when i first playing this game. Persona 4 i don't really like the story (about case), but it's still interesting and emotional about every protagonist character feelings)
I'm playing so many (like star ocean 3, tales series, final fantasy series, tales series, suikoden series, final fantasy series, radiata stories, atelier iris series, mana khemia, kingdom hearts 1 & 2, grandia 3, etc)
Star Ocean 3 is flawless.
Tales of Legendia (this game has many humors, although the battle system isn't really interest me)
Tales of the abyss (emotional and the songs is good)
Suikoden 2, i like the most in suikoden series (there are many suikoden fans who think so too).
Suikoden 3 has many different perspective.
Radiata Stories is unique, i hope they make radiata stories 2
Wild Arms 4 & 5 (HEX battle system is fun)
Wild Arms 3 (the leader is a girl, and she's cool) although the story is not really interest me
Ar Tonelico 1 and 2 (the songs is so good and touching)
