Well, in most of my proto-TL's, I have usually made sure that there is no version of me there because of the butterflies. I usually have a thing againest creating such an alternate version of myself in my TL's.
There's a little story behind that, actually.
My very first tries to create an alternate TL were when I was still a kid
somewhere between 10 and 12 years old, and what gave me the idea of creating a separate TL was the notion of time-travel.
And ever since, I have been adding new scenario's and modifying old ones. In those scenario's, I travelled back in time somewhere in the future to a period of about a million years ago. There's a whole lot of stories that I came up with on what would happen to me next, but the bottom line of all these stories is that due to countless biological and technological enhancements, as well as some really otherworldly cloning experiments, this imaginary version of myself evolved into this amazingly complex being.
Yet because of the whole time-travel thing, I quickly saw what would be inevitable in a universe in which I have traveled to the past, yet survive up until the point that I will see an alternate version of myself being born.
I was then confronted with the question:
should there be two independant Rolves in one universe? (-> Rolf is my real name...)
...because of the whole wacky cloning thing, there was already one "independant" Rolf clone in my TL/Universe, and he was specifically created by some other scientists in the earliest phase of the whole TL/story to stop and replace me.
As it turned out, he not only murdered a number of my comrades in that story (that I like to call "the Genesis Story"), but he also turned on the scientists who thought that they could control him, with equal ferocity, and equally gory overall results.
In the case of an alternate version of myself being born in that universe,
I would not fear that it would become evil and dangerous like that certain clone.
But it would be a rather awkward
Would I have to go through all the same mistakes and embarrasing moments again?
Would I (the alternate me) have go through the same gargantuan process of that evolution all over again?
Or would the alternate me be forced to live a life of mediocrity,
and die a being that is far less then the "original" version of me in that TL...?
In the end, I decided that effectively babysitting an alternate version of me
would be just not what I would want or need, especially since I rejected the notion of the closed timecircle.
So I simply discovered the butterfly-effect, and used it to make sure that I
was never born in that certain ATL.
..
But especially in the last two years, I've been creating scenario's about my future in future TL's, and especially some scenario's on the period between today and the point of me travelling back in time to start creating my own TL.
Yet most of these scenario's are just plain interesting "What If?" possebilities.
And some are just really good stories.
The WWIII veteran future version of me is an example of that,
as I combined a few good scenario's and idea's I had with the scenario of the
Martian Independance thread.
And there's also a bigger story behind that, especially regarding the Third World War and the Arqenaian Empire that I mentioned there.
To mention a few basic details; the Arqenaian Empire is founded by adherants of a new philosophy and new (somewhat Christian) religious movement that is known as Mor Archanon Christianity, which is my own creation and which is based upon my own ideas.
And in that Martian Independance scenario, I was originally one of the founders of the Mor Archanon religion, yet I became pretty much left the ideological as well as political and religious leadership of the movement, because of the trauma's from WWIII, and the way that those traumatic events made clear to the alternate version of myself that I could not ever change humanity, and that it was futile and foolish to ever think otherwise.
The Arqenaian Empire was (like all factions in this scenario) heavily involved with the genocides that took place in this war, even though it was not the original intention of any of the Arqenaian leadership or the Mor Archanon religious leaders to actually start killing off large populations of hostile people.
In that Martian scenario, the future version of me has given up any position of leadership (real political leadership was already in the hands of a number of followers) and he joined the militias as an officer and a fighter/mech pilot already during the last two phases of WWIII, at first in a desperate attempt to change something about the situation, and in the end just living from battle to battle, seeking to escape his traumas.
