If you can believe it, I didn't know what you meant by "deep purple". I thought maybe it was a graphics engine. I'm listening to "Deepest Purple" and so far it is rockin'.
I've tried going back to Bioshock Infinite and still didn't get into it, for whatever reason. Might have to try a third time. I enjoyed the other Bioshock games.
Looks like I'll have to add Spec Ops: The Line to my list of games I want to play.
