I beat him with Joe Quincy from The West Wing, Nora Estheim from FF XIII, Yvonne Strahovski, Anna Gunn, Krew from Jak II, Jim from Mogworld, Killabilly from Lollipop Chainsaw, Elika's father from the PoP reboot and Bertrand from Dragon Age II.
I get the feeling Akinator is stupider than a couple years ago. When I made him guess Bertrand, he asked "Is your character from the Dragon Age series", which made me think he was going to guess Bertrand soon, or at least limit himself to DA characters, but a few questions later he asked me if he was created by Square Enix, and then by Blizzard. Then he asked me if he has been on CSI Miami. Then he "guessed" some dude I don't know from The Witcher. What the fuck.
He did guess Dan Fortesque in six questions, though. Gotta give him credit for that.
