It's no bullshit. You guys are experienced players right? Did you get stuck in a dungeon? Probably not, you can blaze through them because they are VERY straightforward. Same goes for the rest of the game. Or were you all wasting hours on fishing and the ball-maze game?
I used a guide indeed, because I have that awesome hardcover edition (will get the SS one as well). Would be pretty stupid not to use it since I had it anyway. Only used it for those collection guides at the end though when I finished the main quest. Wouldn't you do it as well? There were so many titles coming out at that time it wasn't even funny.
I'll admit I was a bit harsh in calling 35 hours bullshit but it still strikes me as odd because those times don't say anything and are usually way off for me. Exceptions being Xenoblade this year and the Elder Scrolls games.
