Multiplayer in everything
It wasn't that long ago that multiplayer in games was a rarity. Sure, there were games like Battlefield that embraced it, but most games focused on singleplayer experiences. That not the case anymore. Almost every game has multiplayer strapped onto it, whether it fits the game or not. Despite what some industry execs might think, not every game needs a multiplayer component. The indie scene is actually doing a great job of demonstrating this.
