My current record for beating Zelda Twilight Princess is 19 hours.

Is it possible to beat the game in under 15 hours?

i have beaten it in 13 hours without doing anything unnecessary.

12 hours 54 minutes without doing anything unnecessary.

First time playing the game, no help from "the outside", no internet spoilers, and completed 100%… just over 75 hours.

Best Ive done so far is 43 hours but thats getting 100% completion

No its not possible to beat zelda in under 15 hours because there are to many things that you have to do or you dont have a chance with ganondorf one time i could have had it beat in 13 hours but i didnt have the right things to beat ganondorf

thats impossible unless you knew the 5 major cheats of the game

you cant its imossible there are way to many hard bosses

uhh...60 hours.
But i looked for everything in it.

Too many hard bosses? All the bosses are pretty easy... This is coming from a guy who playes too many video/computer games though. I think my best time is like 20 hours or something like that. I haven't ever played it to get the fastest time however. My original time to beat the game was 38 hours though.
