After putting quite a bit of time into it, I can confirm that Ni No Kuni is the best PS3 exclusive available, better than Uncharted, better than God of War, better than any Sony only game out there and - easily - the best JRPG this generation and quite possibly my favorite JRPG right next to FF7. Simple as that.
Tbh as i was watching the video you posted i kept thinking of FF7 and how this game looks like it keeps alot of the charm of the old school FF games but still making it new and better. Something i wish the new FF games did.
Im going to have to buy this game...
Btw my favorite game ever goes FF7 > Metal Gear Solid > Chrono Cross
(Kingdom Hearts and Legend of Dragoon are also somewhere in the top 10)
