Have you heard of the online web comic called homestuck?
I've read Homestuck up to a certain part and lost my place. But I know a decent amount about it. It's a web comic about these kids who decide to play a game. However, they are faced an opponent, who are aliens(which are called trolls). In the game, after they start it, a meteorite crashes into Earth and makes it look deserted. There's noone left but the four players. And on the troll universe, they're pretty much fine(I think). Whoever wins the game, which is called Sburb, gets to make a new planet of their own with their teammates living with them. And by this I mean, trolls are against the humans(if trolls win, they create their own planet, but if humans win, then they can make their own planet). However, the trolls decide to make two teams. That's all I can pretty much explain. It gets really complex throughout the entire comic. And it's not really a comic, but it's close to it. If you are curious, I can provide a link.
