Before the September Direct, it was only Hayabusa, Nightmare, Cooking Mama, and a Dynasty Warriors character like Zhao Yun or Lu Bu since this was before the announcement of more DLC characters on the way and the Fighter Pass felt a lot more dire back then. After that announcement, I started looking into more characters that I'd like to see in Smash, so adding on to that small list was Francis York Morgan, Ryza, Layton, Sol Badguy, Aiai, Geralt, Byleth, and Jacket but as a Mii Costume since Hotline Miami probably doesn't fit with Smash.
Out of the 11 franchises since Hotline Miami techically doesn't count, Dynasty Warriors, Soulcalibur, Guilty Gear, and The Witcher are the 4 series I think are likely to end the current Fighter Pass on, so it's only a matter of time until I get either 1 - 4 or 0 - 5.
