What even is this game about???

I think people like it for various reasons but for some its just a relaxing way to pass the time, and for others its really stressful and competitive.
It's basically a game of tug of war between the two sides, but it has RPG elements that reset at the end of each match, so its a mix of big picture strategy and smaller levels of action to get to the end. Everybody sucks at it when they first start, for at least the first month, but you could always try it out and get through the tutorial and the matches against the AI if you want an idea of how the game works. Honestly its hard to explain or enjoy until you play against other people and start to learn whats going on.
