I am of both sides. I play for the story and the choices and such, and take a long time to play... But then after I've seen everything, I like to dick around and see all the ways I can lose, and how fast I can get certain things or how early I can complete the game. For example, beating Chrono Trigger the normal way is cool and all; but have you ever defeated lavos the very first instance you can attempt it? It finishes the game super early, but it's also the hardest challenge the game offers.
