People still discuss gameplay and expect damn good gameplay for their money. Examples of gameplay topics in the more recent JRPGs:
FFVII - materia
FFVIII - magic syphoning, junctioning
FFIX - ineffective limit break system, skill acquisition
FFX - no world map, blitzball, CTB, sphere grid
FFX-2 - ATB, dress spheres, missions
FFXII - gambits, liscenses, loot
FFXIII - paradigm shift
Shadow Hearts series - judgement ring, combos
Last Remnant - units, drilling
Lost Odyssey - skill acquisition, levelling caps
Enchanted Arms - golems, grid
Infinite Undiscovery - party compatability, item creation
Eternal Sonata - light/dark moves
Blue Dragon - battle initiation, three way battles
Magna Carta - combo input for any move (I fucking hate that system, first and only time I have ragequit a JRPG within 2 hours), area chi
Magna Carta II - Kamonds, kan, chain breaks
Retro gamers and people who just don't like JRPGs, for Jeebus' sake, JRPGs are not a copy and paste affair. They all share similiarities, given they're from the same genre, but you can't expect to walk into a game and instantly master the gameplay. In fact, JRPGs are quickly slammed if they're too base; Lost Odyssey has been equally slammed and praised for its old school turn based approach, and Dragoneer's Aria for PSP is one of the most dull, uninteresting modern JRPGs you can come across because it offer NOTHING new (and battles are painfully slow).
