Played so many JRPGs I could never count them.
Claming that KH combat system is basic is objectively out of place, especially considering it was first released on PS2 and very few games were like that.
I understand that most JRPG fans are bound to the (actually-not-so-much) tactical turn-based system and see everything that is not turn-based as the "casual gamers stuff", but this is just asinine. KH's combat was built and enriched with several ispirations from various genres and includes lots and lots of options for the players to use (hack 'n' slash melee, magic, reaction command, evocations, drive gauge, party members aids and combo). What about is basic, for Heaven's sake? A "basic" action RPG is somewhat of a Tales Of, surely not a Kingdom Hearts game.
And by the by, I say this as a mudslinger of the series... It really has gone downhill with the III chapter and was already headed that way previously. Not exactly in the mood of defending it but sometimes I ask myself where the heaviness of such claims comes from.
