okay, I'll STFU because I should, it should be a 'qualified success', as it hit #1 in the UK and that's damn unusual for a JRPG. It could outsell Devil May Cry there, and hitting 70-90K still puts it leagues ahead of anything that comes out of NIS, Atlus, Aksys, and the like.
I forgot that Blue Dragon, Lost Odyssey, Valkryia, Demon's Souls, etc. benefited from great timing, money hatted marketing, terrific reviews, and such. But all of those are still years in the past. Ni No Kuni is still kicking ass, rocking the Amazon chart (for whatever that's worth) and probably exceeding the rather modest expectations placed upon its Western debut. I'd call that a success, but I should temper my enthusiasm.
