I think you have to take some things into consideration. Most games first hour sucks because you are mostly busy with some tutorial and shit but you say meh the rest of its 10 hours will probably be good so you accept it. For a game like final fantasy the numbers are just a bit higher, you'll easily spend like 50-100 hours in the game, so 10 hours in comparison is less bad than it sounds. Granted, it was too long but if you drop the game because you didn't like its first hours, you are missing out on the like 40-90 great hours.
On the other hand a game thats only 12 hours long and only one if it is actually good, than that game can be rightfully called trash.
10 hours and a RPG should be able to kick off right away because every RPG kicks off withing the first couple of hours it is about a hook that makes you want to stay. Xenoblade did it within 3 hours and tales of vesperia for me did it within the first 2 hours for me. Wont go into XIII no more but all I can say it did lack a hook for me to care but thats enough about that. I believe Versus should be ok because its well... a real time system with a nice looking atmosphere. xD
