I don't see why people compare Fortnite to PUBG and complaining about being a copy. Of course it's a battle royale game mode, but that's all. This game mode existed before PUBG.

Fortnite BR is so different in weapons, fights and building and even with all the hilarious skins and dance moves.
It's much more fun to play this and it's by far better optimized than PUBG. If they keep up the work I think Fortnite will be around much longer than PUBG.

So I guess we may see it for a while on top of Twitch but you never know what comes around next. I'm really looking forward to :-)
