“Have a pleasant time in Equestria,” the old man said with a wide grin.
Yellow electricity leaped from the sword, curled up my arms, and sparked in my ears like a cracking whip, but I heard the word Equestria clearly.
You see, I forgot to tell you. I'm also a huge fan of My Little Pony. So I was pleasantly surprised when I heard the news. I loved Equestria and its inhabitants. They were some of my favorite characters in all of pop culture. Spending time with Twilight Sparkle, Rainbow Dash, and Pinkie Pie for the rest of my life wouldn't be too bad. We'd have so much fun together, assuming we could figure out our differences.
I didn't have much time to comprehend it, however, because in the time frame of a fingersnap, I blacked out.
I awoke to the sound of roaring wind. I opened my eyes with strain, and tears leaked out and flew past my head. Beneath me was a minuscule version of the Castle of the Two Sisters, dilapidated and in ruin. The ground was getting larger by the second.
I was falling.
I screamed and flailed my arms helplessly. The ground was only five hundred feet below me when I understood my situation. I wouldn't survive it.
I hit the flagstones of a castle battlement on my spine, and pain blinded my senses. I bounced off it and plummeted even more before smacking my skull into a staircase. I bounced step after step like a clown and hit the stone floor hard.
Then I died.
I do have to wonder, why is it the characters almost always end up in the Everfree Forest these days, near the Castle of the Two Sisters? I mean, come on, can't they end up somewhere else... Like, say Griffonstone or whatnot? I mean, Equestria's not exactly short on locations is it?

I would hazard a guess as to why: because the Everfree is the most similar to Earth. The weather behaves on its own, the animals are rabid, and the plants grow unsupervised. Because of this, the closest connection between Earth and Equestria is the Everfree. The interdimensional traveling just takes the shortest route from place to place, like lightning striking the tallest structure.

I know of a few stories that start up elsewhere as you ask, but I think it is like Brady said - it has wild magic, and seems too similar to Earth to be a coincidence.
And many authors are lazeee, with no creativiteee.

Because the authors are lazy. No really, it works under assumption that the environment of Everfree forest would closely resemble the Earth.
