*Fortnite
It's an online game of the battle royale in which you are dropped on an island and you have to eliminate the other players. The last man standing wins. One thing that sets Fortnite apart from other games of the battle royale genre is its cartoony visuals and its building mechanic. You can build forts, towers, and other things.
The game starting trending in early 2018. It still is very popular to this day.
