I may be in the minority, but I think it would be nice if the game took place over a few days instead of all in one night. They could maybe throw in a couple of day sequences where you have some mission to accomplish as Bruce Wayne or Matches Malone. These could be used to flesh out the narrative as well as adding life to the city by showing its population occasionally.
At the very least, at night we could see more police patrolling the streets and maybe actually see them accomplishing something against the thugs on every street corner. It seems that so far in the series, you only really see the cops when you are either saving their butts or they are trying to kill you.
