Soulcalibur was one of the first games I managed to emulate on Demul, back in 2007, and I’ve been playing it ever since ocassionally.
But I never knew that the arcade version was actually inferior to the Dreamcast one, which almost never happens:
Also, I was under the impression that every time you completed Story mode for a character, you unlocked their “twin”. Mostly those were reskins, but some of them would grow into distinct characters later. Turns out that’s incorrect. You open charactacters based on how many times you finish the arcade with distinct characters, not with which character you finish it. Yoshimitsu always opens after 2nd completion, while Cervantes requires 10.
