This is a 20Q game that so far is the best I've found.

He was able to guess Magus from Chrono Trigger, ana Aya Brea from Parasite Eve. He even got Dante from DMC before reaching the 20th question.

This guy even guessed Shoop Da Whoop. WTF.

Yeah, I've only found two things that the thing didn't get on the first or second try.

Megan Hollingshead

And Flammie.

Everything else he gets in at least 2 rounds.

This thing is a monster. I couldn't find anyone he didn't know about.
Then I threw everything to hell and tried the freaking Brazilian president, and then he got that right.
So I chose a Brazilian writer (Luis Fernando Verissimo) next and thank god he failed. But his guess was a writer, only a much more popular one and a much worse one (Paulo Coelho).
And then Verissimo's name is right at the top of the "then tell me which character it was" list. I'm freaked out. This thing is satanic.

I love how the "top characters" include "you", "the yes-pressing person", "the one nothing is known about", and "your mother".

He was able to guess Will from Illusion of Gaia.

And one really scary moment, I was trying to get him to guess Ramza from Final Fantasy Tactics. He started asking questions that lead to Squall, then Cloud, then Zidane... and right when I was thinking he'd mess up... BAM. I got owned, he guessed Ramza.

What the f*ck... I thought of Rita Mordio from Tales of Vesperia... and he guessed it right.

OK, I think of
Rainbow Brite
Beth (from Total Drama Island)
Chapulin Colorado

It only got Beth wrong.

Heh. He can't think of Suikoden characters, it seems. Couldn't get Viktor, nor could he get Chris Lightfellow.

I put in Dr. Wright from Sim City, but he thought of Dr. Stiles from Trauma Center.

Edit: Nor Strider Hiryu.

That's awesome Guar, I just tried the weirdest TV character I could think of and he got it right.
It was Chapulin Colorado =P

Edit: Okay, this thing is satanic. It got "your cousin" and "a very beautiful girl in your close cycle" right. When I thought about "the voices in my head", the guess was "your soul".
I'm scared.

I thought I'd get him with Chapulin Colorado until he asked "Is your character associated with red?" followed by "IS your character from Latin America?"
But I got him a few times
He guessed Tom Nook when I thought of Duck Hunt's dog (But I thought I was screwed when he asked if it was a Nintendo character) and Mighty Max instead of Captain Nintendo.

EDIT: Anyway, it even guessed Chris Crocker. Chris Crocker! I'm not sure he managed to guess one of the things I thought of in a desperate attempt, but it did ask if the character I thought looked like a snake. >_>

I had fun on there all day today. Even got some other friends interested in it

... Hah! I defeated him on the first attempt. He was no match for SK's craftiness!

You probably picked some anime chick that most people have never heard of.

What the hell... he just got Gnome the Snail from Soul Blazer.

Also got GLaDOS from Portal... it was actually kind of hard to answer some things correct... like is GLaDOS a female? It has a female voice, but it's a robot, so yeah.

He guessed Jack from Bioshock too! I answered 'no' to just about everything. And you never really even SEE Jack. You are always in first person... so how he guessed this, I have no freaking clue.

And Tim Buckley, creator of the web comic Ctrl-Alt-Del...

And video game podcast host Tobin Coziahr from Noobtoob. (Though it took a few rounds for him to get. I'm still very impressed that he even eventually got him.)

::edit::

Just messing around some more... he got Laharl from Disgaea, Hunk from Resident Evil (took him two tries), Alphonse Elric from Fullmetal Alchemist, and Bob from Reboot. What was amazing about Bob was that I had to practically say 'no' to every question as he was way off most the time, how he got it, I have no clue.

Oh, and a broke him once. Tried to get him to think of Felicia Day a few times and then he got hung on "I'm thinking of..." perpetually.

Also, and you should play a game JUST clicking "probably not" to see what happens.

murrr i kinda like Paulo Coelho.

and ive totally seen this akinator thing before.. but i think i found it when i was searching for somethign totally different @___@

and he totally failed for me cus i clicked 'no' for the first question and his speech bubble just went blank. prolly this sh*tty library computer. =( ah well.

I bow down..

He got the shamwow guy.

Though, I knew he would once he got into the 'was he famous because of television' 'did he have something to sell' and of course.. when I said 'no.. he doesn't have a beard'

Bastard!
