Will the intermediate installs be done during cut scenes so they are not noticed unless you skip a cut scene?
If this is the case I don't see it as too much of an issue.
Also if the installs are to change the direction of the game depending on something you did/chose I think its a cool idea as long as it installs while you are watching a cut scene or tutorial.
I personally don't care for cut scenes or installs, it seems to be getting a bit out of hand. I'll hold judgment until I see the installs in this game for myself.
