Hm...I'd miss advanced technology, the Internet, the familiar feeling of Earth, and perhaps my old friends as well.
But I'd be a jerkass to leave new friends and new places behind forever, as well.
...Bah, if I were given an opportunity to leave, I'd stay in Equestria until there was a method to freely allow travel back and forth between worlds. A portal device, if you will. If that happened, then it would only be a matter of carting my familiar gadgets over into Equestria, and looking into reverse-engineering the stuff to use magic instead of electricity.
Yes...magitechnology and technomancy. What fun that would be!
i'd miss my copy of Xenoblade chronicles and the internet, we may have to get one of thr princesses to come and find a way to get back. because I would not surivive long without playing some Xenoblade or listening to its soundtrack
Why would a human want to leave? Lyra is Cute. The Everfree Forest would have me most the time... fun time to fight wolves made of timber xD Diamonds to easily mine. Equestria, a new place for human adventure!
