Is brawl Stars better than Fortnite?
That depends on the subjective opinion.
That is subjective. There's no better or worse. But definitely Fortnite in my opinion.
You can't really compare an original game developed for the computer / console with a mobile game.
Although I don't like both.
Definitely Fortnite in my eyes, but Fortnite isn't exactly wow either. It just annoys because there's sweat in Fortnite.
