There's little doubt that this growth will slow over time, just as it did for Apex. It's mainly a matter of when that happens, and whether or not the sustainable audience will be enough to eclipse rivals. That's a tougher call. It's unlikely that Warzone will achieve Fortnite's level of cultural relevance, but a familiar name, Activision's marketing clout and solid game mechanics give it a better shot at success than many of its competitors.
