I used to play the hell out of this game back in the day. THe shitty netcode's put me off from buying the console release, but I"d still love to win it so I can practice up and play with the local guys again.
I think it only gives you plus if you don't already have it. I already have Plus and got no extra time, but the fine print clearly states that it gives you 30 days of plus, and that a credit card is required.
