I think it would be more interesting if we can also know how much the ratio of traffic that they bring that turns into monthly active players. If this could bring a huge increase, it might makes other global game company sees that kpop idol was a really viable option for promotion.
If we are just want to assuming things, regardless the real number, then the answer might be companies would start to make a project with a kpop group that had a global reach (maybe stray kids?).
Actually, many game had already used kpop idols as an ambassador, even doing a frequent project with several idols. Those were only in SK tho (E.g. overhit).
The other way around would also works, such a SK game company that want to have an global players will make a project with kpop idols that had a big/huge global audience to promote their games.
The question is, how many kpop idols that had such a big/huge audience globally?
But if we really want to talk about the huge changer, it would be K/DA, a project from Riot games that using Kpop concept as a promotion.
