Fighting game Soulcalibur 6 proves to be a big seller. Bandai Namco’s game is the second most successful entry in the series with two million sales.
Soulcalibur IV still leads the way with 2.3 million sales. However, it is of course not inconceivable that part six will surpass this amount. The game came out in 2018 and has had updates with new characters in the meantime. Think, for example, of 2B from Nier Automata.
