Been playing 2k on iPad since 2k14, and the game keeps improving. Yeah, the controls take a little to get used to, but once you do, its much nicer than 2k15. The "dribble" button is actually a virtual right stick like on physical controllers, which allows you to do much more stuff like floaters, euro step layups, choosing which dribble move to do, and so on.
Two things I have noticed so far: 1) Still no consistent commentary, audio needs improving, at least for newer devices.
2) When playing a season (and maybe quick game too, havent tried it) and the other team calls time out, you see their players and game settings instead of your own.
EDIT: The equipment shop is not in the game yet, really looking forward to it, hope it comes soon!
