I understand you have posted a spoiler warning but please, please, please don't post about the story line. Try and stick with game play.
Shooting and driving takes a bit of time to get used to. Same for working out the cover system. Sometimes it doesn't want to switch targets :s
Love the circle around the area police are searching and the GPS to help you find your way around. It's not perfect, sometimes you can find quicker routes by going through parks, etc but it works.
Handbrake in the cars are extreme! Pull it and just go down the road spinning. So much for turning corners at speed.
It's fairly easy to out run cops if they see you rob a car (1 star) but if you shoot a cop (2 stars) the circle gets a lot bigger. Still easy enough to get away but takes more time. Funny seeing the star get added when you drive through a toll booth without paying. Last time I done it I was being chased by a helicopter!
Blowing the headlights on the cars can be annoying at night. Cannot see a bloody thing.
Graphically, the game seems a bit dull and dark. It can be hard to spot people in warehouse missions. Might try upping the contrast a bit.
Waiting until tuesday but I go online with it, or even sign back in to PSN.
