dabookerman said:8 Minutes = first install, when you start the game.
Then before each act, the time it takes to install is as follows
Act 2 - 3 mins
Act 3 - 3 mins
Act 4 - 2 mins
Act 5 - 1 min
It should be noted that these shorter installs are because the cut scenes in between acts are like mini movies. 30 minutes+ is what I'm hearing and they only have to be loaded once on the first play through.......
