Yes size matters and in this game, the developers didn't think it mattered enough. You can brush through the game in about 5 hours and it could take you 15 hours to find all of the secrets. I was disappointed when i found out the length of the game . It is a good game which incorporates good gameplay, a storyline and humor. The other con to this game though is that it is incredibly easy. But a plus for this game is that it has Infrastructure mode (online play) which is a plus, but you wont spend that much time on infrastructure mode.
A good game that falls "short" (no pun intended) of greatness
