It's like Twenty Questions, but with characters and people instead of things. It is also scarily accurate. Go ahead, try and find someone it can't guess.

That is scarily accurate.
I did Lister and Rimmer from Red Dwarf, and it got both of them first time.
It also got Strelok from Stalker, and it almost got Erich von Manstein.

It failed getting the helping monster trainers from both MR1 and MR2, unfortunately, it was in his list though.

edit: i got it to fail 3 more times.

I added the Coalition light to his database a while back.

It keeps picking "Terran Marine (StarCraft)" when I do the coalition light.

What the ♥♥♥♥, Akinator?

The Dummy and Brain are in the database. I added the Brain Robot.

Akinator is my favorite online toy. Makes me rage when he gets something i think he won't.

It thought Arne was Linus.

yyyeeeaaaa i got it

Wow. It correctly guessed Phoenix Wright. Half-way into the questions, even.

Time to crack this nut.

Due to my sloppy answering, he missed the first time, but successfully got Lain, from Serial Experiments Lain, on his second.

Synyster Gates seems to be a hard one, while the slightly less famous rhythm guitarist got picked out the first time. (Avenged sevenfold btw.)

And coalition after quite a lot of questions.

You need extremely obscure characters, like MLC, it can't Get The generals of ZH.

Or Coup from Megas XLR, it doesent get anyone from that program.
