Lack of Characters.
I’m sorry, no matter what 18 characters is not enough for a base roster. I mean 3rd strike had 19 (20 if you count gill), in 1999. Hell, Tekken 8 has 32, and MK1 has 26. At this rate we’re gonna end up having more DLC characters than base roster characters, like we did in SF5, and DBFZ and now GGS. We’ll be lucky if the next MVC game has more than 20 characters.
