Wow. For a previously exclusive nintendo gamer...id say the PS4 has very little to offer you.
Hell even long time playstation gamers have made some complaints about the games selection.
I agree with the other posters in that you should have already done some research into what games you want to get for the system..otherwise why are you getting it?
In any case...i recommend Resogun!
Edit: I see you have looked into what games to get. Apologies for assuming you hadnt!
