I've just played one fortnite match and I didn't really like. I can understand how most of the people may love it because of the colorfulness, fast matches and a big community of players and streamers. However, I prefer pubg because I honestly prefer "realistic" games such as arma3, where I've got like 4k hours played, and that kind of games. Pubg was initially a piece of crap, without any optimization and I even left the game for a few months, but nowadays it's been improved a lot and can be ran on almost every pc out there.
