First time through, I'll try to see as much content as possible. For example, I replayed Megaman Legends a week or two ago. First time playing it on the big TV. I ended up spending about 15 hours in a game that you can easily do in 4 because I went to the trouble of trying to see as much dialogue as possible. i.e. I went around and knocked on every door in Downtown after every major story event to see if the dialogue changed. I said no to all of the questions when you're expected to say yes. I found a few funny things I had never seen before, like Roll saying "I'm sorry Megaman. I must have misheard you. It sounded like you said 'No.'" after the Marlwolf fight.
