Just wondering because this is genuinely one of the most detailed games (in terms of how packed it is with content) that I've played in a very long time, whether that involves the story itself and all the various what-if scenarios within each character's path, the fact that the encyclopedia entails an hour of girltalk between Chi-Chi, Bulma and Videl (can't find the Japanese audio version), the fact that characters like Goku Black and Baby Vegeta have special interactions if you pick them in a match, I'm just having a lot of fun.
It already has an all-time peak of over 90,000 players on Steam, and this is still early access. The game doesn't even release for the people who bought the base game/are buying it later until 6pm EST tonight, so I can't imagine the concurrent players for the next few weeks.
Akira Toriyama's legacy will live on until the day life no longer exists.
