I thought I was lazy, for some time GoW2 was my most played game, but if I wanted to play another game, instead of putting the game back in its LE case, I'd put it inside the case of the game I was going to play. So if I was going to play Halo 3, the GoW2 disc was going inside Halo 3 case. That's because I thought it was too much work to open the LE case, the ones that have that case know what I'm talking about.
So, now after reading the previous posts, it seems it was a good decision. Finally my laziness is good for something.
