Couldn't you just flip the wifi switch on the side of the console? I think it sends you back home but I'm not sure
I actually threatened to do that at first. I had only just arrived at the island, so it's not like I would've lost anything. I just wanted to try through other means first.
I honestly don't get why the game blocks you from leaving the island when a tour is being set up, when someone is talking to the shopkeeper or even when someone is in their pockets (which is what this person did). It doesn't really cause any problems for the person doing this stuff but it allows for these hostage-taking scenarios to happen.
I'm actually afraid to go on the multiplayer island now. Actually, I'm nervous to even open my gates, I've heard sometimes people can enter your town when you haven't asked them to. I thought it was Friend Codes only in New Leaf. If people without your Friend Code can enter your town, then that's a problem as people could do the same thing there as well, and could ruin my town and stuff.
That's right, only people you've traded friend codes with can access your town.I'm pretty sure only people with your friend code can enter your town, so randoms just wandering into your town shouldn't be a problem.
