The problem with this lawsuit is simple: You can’t copyright a gameplay mode or genre. If this was the case, every tabletop RPG after Dungeons & Dragons would have been sued into oblivion. Every first-person shooter after Wolfenstein and DOOM would have been hit with a lawsuit. It’s like trying to copyright basketball or hockey. You can’t do that. Also it’s a very bad thing for PUBG aswell seeing If fortnite looses the lawsuit, Epic Games still owns Unreal Engine 4 which PUBG uses. I’m still scratching my head over the whole thing. I’m not sure what PUBG Corporation thinks they can achieve here. I’m not sure it’s a very smart idea to sue the company whose engine you happen to be licensing for your own game.
