Brings up the interesting connotation that millions of players are either gigantic womanizers who go from one set of heroines to another, or conquerors who have many passions in their lives. I'd say mostly the former, a little of the latter.
As well, pretty awesome to have the main characters have memories of previous games in fanworks. From Kantai Collection, to Girls Frontline, Granblue Fantasy, Azur Lane, Fate Grand Order, Fire Emblem Heroes, Arknights, and many more, so many protagonists would be considered Forevermen.
