Not a good look releasing this model right after Apple Arcade. It's not unusual in the mobile space, it just looks especially worse now.
Also locking 200cc behind among other stuff it is pretty fucked up. They probably would have been tolerated better if they went with the standard gacha practice of charging you a sub fee, and you just get more gacha currency for it, instead of locking all of this stuff out.
Or they could have just made it like a 3$ sub or something. With something with as mass appeal as MK with that price, it could have definitely worked and made up with it being cheaper just through the amount of subs, and not seemed as bad.
They went about this pretty poorly. It's like they weighed all their options and went with one of the worst ones at the worst timing.
