I don't know if this has been brought up before, because, clearly, I didn't read through 76 pages, but, we now know that icon 13 is a spacehold for Game&Watch, so basicly, I just don't see another reason for another gap, 19 has to be a spaceholder as well, but then again, the Brawl franchises don't seem to have any order at all, so why spacehold there?
In short, the main question we need to answer is why the spaceholder-19 is needed, and not what the order is(Even though that'll help alot too).
Again, sorry if this has been disscussed already ><
