This game has over 40M users and is the biggest game out right now, so it's obvious the mobile app launch will be huge. That said, it's never going to get priority over the console/PC versions. While it's good that they're expanding and all, the mobile version is there more to compliment the console/PC versions, thanks to the cross-platform player progression. Existing players can play on the go and keep working on their progression when they're not at home.
This game doesn't really need any more exposure, but Drake appearing on Ninja's stream definitely opened more doors and is most likely the reason for the increase in youtube views. To have one of the biggest musicians in the world playing with one of the best players in the world is huge. Not gonna lie I watched it for a bit as I'm a fan of Drake's music and the game, so it was pretty entertaining. Not to mention Travis Scott (another big rapper) and Juju (NFL player) also being on the squad made it even more epic. And it's not like this was just a publicity stunt, all of these guys actually play the game.
They were able to smash the single streamer viewer count at over 600K viewers, and this was basically at midnight. Ninja has exponentially increased his viewer/sub count thanks in large part to this game. With the twitch prime exclusive Fortnite skins skins, Drake appearing on his stream, and Fortnite blowing up, he has something like over 200k subscribers and is making over $500K a month just on subscriptions alone. Obviously all of those subs won't stay, but that's pretty insane considering most big streamers only get a fraction of that.
As I improve in this game, the more I enjoy it. It has a really steep learning curve with the building (which is a huge part of the skill gap), and people keep getting better and better. I consider myself pretty decent at MP games, but I honestly don't see myself becoming really good at this game... the building in high level play is just too much. That said, me and my squad still get our share of wins and I'm loving the game. I have to mostly rely on my gun skill, and my building is just good enough that I can hold my own and protect myself. I can't really play how I want to play, which is aggressively, because the controls are just too complex for me to be able to build and fight fast enough. If I ever get there though, I think it will become pretty decent at it.
