2K's card battling NBA 2K15 companion app has arrived on iOS and Android so that you can, er, battle with basketball players, I guess.
MY NBA 2K15 seems to be what we get this year instead of, say, an actual basketball game like last year's NBA 2K14. Whether we'll get NBA 2K15 on mobile is something we'll have to wait and see.
In the meantime, we have over 1000 player cards to form into teams and to compete with through the art of imagined basketball.
By that I mean you don't actually play or see basketball, but have it told to you through the medium of cards. You do, at least, have to lay out the cards in the formation you want your team on the court.
In essence, it's a card battler but instead of fighting you move through a basketball season 'battling' against opponents of equal skill.
You can customise a card's strengths with the available slots and use "Season Coach Cards" to give them a boost.
You can also browser the "console store" and purchase items that transfer to NBA 2K15 on console.
If you're into card battlers, or are playing NBA 2K15 on console then you may want to consider picking up My NBA 2K15.
