Stumped it utterly with Colonel Tigh from Battlestar -- thought it was Mal Reynolds (20 q's), Kryten (30), and some old wank from Stargate (40). Way to insult my intelligence on that last guess, internet game, although at least by the last one it had figured out he was old. Anyway, websites just have no taste these days. It also failed to identify Davos Seaworth, guessing Thorgal. Who? I attempted Wolfgang Grimmer, of Monster, and the game gave me... Jonathan Joestar? After 30 questions it guessed November 11, from something called Darker than Black, which seems at least to be more stylistically similar.
It (surprisingly, given how off-base it was for most of the questions) got Desmond from Lost successfully.
These sorts of games are fun, but I've played ones with a more impressive rate of success. Then again, I guess my taste just doesn't intersect that much with most of the players.
