LOL, you are a harsh critic.
On a side note I have started playing that Dragon Quest XI and am coming to the same conclusion as you. Starts well and then by Lvl12 it goes a little flat.
Having played both this and Ni no Kuni, you might want to avoid both and Ni no Kuni 2, as they play out in a similar manner. I do like the crazy stories though.. and the DQ one.
They are always bizarre.
