Sure it makes the game look flashy, but I think that was mostly the case in Zero.
Without the the BGA preview in Zero, the theme would look extra boring.
And it got smaller and smaller in NX to NX2, to the point where it's just some small square you don't bother watching most of the time. Not saying it should be taken out in the next mix, maybe just make it more integrated into the theme.
Or something lol.
