You know how some games have unlockable concept art or sketches or development notes whatever? Am I the only one who takes the time to just sit back and flip through everything?
I notice Mortal Kombat's been doing it a lot as well as the newer Naughty Dog games like Last of us or Uncharted and Sonic games. The latter of the too has some really colorful sketches.
I think more games should put these kinds of things it just to enjoy.
