So he starts off in a shipwreck on the beach, he enters a dungeon, after completing the dungeon he enters the nearest city and masquerades as the mayor (who was supposed to be a child with similar features to him who died during the ship ride). The world (I think) drags in professional players into the "game" and the MC can offer the players main/side quests and he can set the icon of the app on the players ones and stuff, he's basically the game master, the first quest they get is right after they enter the world, they're tasked with killing off a group of people carrying explosives to destroy the city who were sent by a neighboring mayor. Thanks in advance
