Been There, Done That Challenge - Let's play our game!!!

HOW DO I DO IT?

You may have seen that this challenge was posted weeks ago. Since then I’ve been researching and adapting the rules. Suddenly, it was clear to me that the game is way too big to set to many rules.
So I decided to do as follows:
We first create a Sim (can be in CAS or you can just take any pre-made).
Then we crossbreed our Sim with a Sim with a different Life State. The kid, we crossbreed again with another Life State until we have all of them. Our last Sim, the result of all Life States, will be last Sim of this Legacy.


PHASE ONE: Creating a Sim
We start by creating a Sim in CAS (or using a pre-made Sim), our Sim-Founder (gender and race are your choice)

STEP TWO: Crossbreeding
We start playing and breed our Sim with a different race (or Life States). The result (the child) will crossbreed with a different race, and so on, until we have our last Sim, which is a result of all races we have in game.

Note:
At this phase, we start also "collecting" our achievements. Everything we do here, our final Sim, the Omnipotent one, won't have to go through again (he can, but he doesn't have to). During this phase, we can use many traits we don't want our "Last Sim" to have.

Life Time Wishes & Carees:
There are, I think 86 different LTW and, unfortunately, once fulfilled, a LTW cannot be changed anymore.
Here thought on two ways to get them done:

1. Combining this challenge with another (as long as it won't break the rules of either challenge. I'm combining with "Going Solo, by Vuneca", in which we go through all LTWs.
2. Using the other famili members LTWs (parents, siblings, etc).

Nevertheless, no matter what you choose to do, this may be quite a long phase, since there are a few races until we get to the final one. They are:

List of Life States:
(as they were released)

1. Human (Base Game)
2. Ghost(Base Game and as CAS in Supernatural)
3. Mummy (WA)
4. Vampire (first in LN and as CAS in Supernatural)
5. Imaginary Friend (Générations)
6. Genie (Showtime and as CAS in Supernatural)
7. Fairies (Supernatural)
8. Werewolf (Supernatural)
9. Witch (Supernatural)
10. Alien (Seasons)
11. PlantSim (University Life)
12. Mermaid (Island Paradise)
13. Plumbots (Into the Future)

Notes:
1. I’m not sure if it’s possible to breed with Life States Mummy and SimBot. If not, then your Sim needs to temporary become a Mummy and create a SimBot and a Plumbot.
2. I didn't mention Toad Sim and Zombie because they're temporary states.



STEP THREE: The Omnipotent
Here we have our Sims ready, the outcome of all races we have in our game. This is the one who will walk the final path!
I call him Omnipotent, because he carries the blood of all races. He can what no other can. This last Sim has the power of all other races withim.
This last Sim will finish what the others before him couldn’t.




ACHIEVEMENT LIST/CONTROL:


Since there’s a very long way to go, you may want to write an achievement list. I'll do it myself, it's a good way to keep in mind what we’ve already done and what’s missing.

You may open a separate thread and write it in there.
