It's funny you think in-game NPCs would put an end to a real-world video game. I mean, I agree with you in that I don't think everyone would want the city to be under attack all the time, but it's still funny. I imagine it would be an event you can choose to participate in, then you'd simply lose XP if you lost the event. It wouldn't ACTUALLY put an end to the video game. Lmao.
