Controversial! No, seriously, though. There is no excuse for Ni No Kuni.
"But it was gorgeous!" "Studio Ghibli did the animation!" "It's so whimsical!" Yeah, OK. It also has the most broken battle system of any RPG released this year. Your companions' AI is so dumb, they'll use up all their magic casting buffs, then be unable to heal you—even when you tell them to stick to healing magic. Or they'll cast all their most powerful spells at peons, then spam their weakest, most ineffective attacks at huge bosses.
When the best option for combat is to grind until you're over-leveled, then kill two of your characters so they don't get in your way, you've got a terrible game on your hands—regardless of whatever positive properties it may possess.
