That thing is.... impressive!

It got Mark Corrigan from Peep Show in 22 questions - pretty cool
It got Kyle Gass from Tenacious D in 19 questions - again, not bad.
It got all the Bleach characters I though of in under 20 questions.

By this point, cool, but the novelty has worn off. Then, what surprised me is how it knew my train of thought and when I would do it.
For the last one, I thought, let's see how many questions it takes to guess itself (Akintor).

The first question was "Is your Character a grown man?" I figure yes.
The second question was "Is your character a genie?" WHAT THE ACTUAL FUCK?! I put yes.
The Third question was "Is your character asking a lot of questions?" By this point I am literally rolling on the floor pissing myself in disbelief.

EDIT - Just had another few goes. Took him 49 questions, with an incorrect guess to get Alys Brangwyn from Phantasy Star IV. That character has only been played 160 times, which is nothing compared to the thousands for the others I tried (Samus Aran was something like 25000 plays).

Leads me to think this: Lets see who can think of the most obscure character, that would take the Akinator 100's of questions and incorrect guesses to get, along with the fewest plays. Interesting, no?
