Here are some possible Similar Worlds Introduction

You're traveling through another dimension, a dimension not only of sight and sound but of mind." It's like the opening line to Similar Worlds setting up all the weird and wild stuff that's about to go down. So, if you're ever feeling like you've entered a strange new world, just remember, you might have crossed over into... Similar Worlds.

You're traveling through another dimension. A dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are that of imagination. That's a signpost up ahead: your next stop: Similar Worlds!

You unlock this door with the key of imagination. Beyond it is another dimension. A dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into... Similar Worlds.

There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call Similar Worlds.
