Why are people stamped playing Fortnite?

I think that's really stupid… Sure, some are addicts and so on, but with people who only play it for 2 hours a day? Especially now during the holidays.

Because Fortnite is a game that has got the reputation of being overrun by little kiddies and cringe streamers. Is just the main group of players. This has nothing to do with addiction, here the average age and the expected maturity are laughed at. This is even recognized and exploited by the developer himself.
