While the plot seems interesting, it gets old rather quick, the minor tweaks do noting to disguise the fact its still the same game from ten years ago.
Also your arguements on DragonQuest and FF are a bit off. First how many DragonQuest games even get to go outside Japan? Their market is the only one that like the same style over and over. Personally I like FFX, and FF12, hated FF 13. For me 12 was FF at its height its pinnacle, the way the series should have evolved and should have kept on evolving, but noooo they actually devolved it for 13.
Does anyone know why 13 was crap and played liek something out the dark ages? Because all the hardcore turn based RPG fans hated 12... WTF? Japan and its RPG's have never caught up to modern standards. If you look at Infinite undiscovery, Lost Oddesy, Enchanted Arms, or other console RPGs from Japan, you'll see that aside from very slightly different battle mechanics their all basically the same. No evolution.
Ironically Pokemon's problem is they have never "Evolved"(LOL pun intended

) in 15 years.
