Here is some common sense.
Fortnite is way too big, plus it's free.
We don't know if Hytale is free or paid yet so here is my theory.
If Hytale is F2P it could stand up against Fortnite IF HYTALE IS A GOOD GAME. AND I MEAN GOOD.
BUT from the way things are going I doubt the Hytale is going to be F2P so I doubt it will be anywhere near as big as Fortnite. 78.3 million monthly players. (around Sep 2018) that is 36.3 million more players than PUBG has per-month.
You really gotta think about this.
That amount has probably increased from 78.3 million. The game is probably the most popular online game to ever exist.
When you mention views don't compare anything to likes, that is incorrect. If you think about it more people know about Fortnite more than Hytale. I can assure you that most of the population knows about Fortnite as it has been everywhere.
