What game are you trying to play?
Is it disc-based, or digital? Digital
Please describe what happens when you try to play. Include error messages & codes, and as many non-personal details as possible. There are no error messages or codes. I launch BF4 from the home screen, it loads the splash screen (rainy city skyline) for 5 seconds or so and goes back to the home screen.
What have you tried to fix this so far? Please be specific. Saying you've tried everything doesn't leave us too many options! I have uninstalled the game and re-installed it.
