Super annoying login process which you cannot skip even to play in arcade mode, or something quick and easy with two controllers, which was the reason I bought the game.
Once I worked through the registration process I still couldn't log in; persevering, could not receive an email to activate the account.
Although I know all game manufacturers are heading this way, this has been a poorer experience than the usual data-harvesting life-invading garbage from companies over-reaching and over-estimating their importance to casual customers.
2K for me now is a cannot buy brand and I'll look for a refund, even though I'm not that bothered about the cost, but doubt I'll get one.
