I always thought it'd be great to have a zombie apocalypse, and a soulmate to undergo the trials with. I'd enjoy it partly because I dislike crowds, but mostly because of the freedom. I'd fill a backpack with rations and water, and leave. Nobody could tell me no. I could climb a power station, or explore a military base. There's nothing off limits, without someone to tell you not to. I'd probably get myself killed, but hey... I'd like to live, not grow up, pay my bills, and die.
Don't forget you can sell towers if they're in the way!
