So Here's the Thing

Since I live in two places, I am unable to play the Sims 2 all the time. Unfortunately for me, I live mostly in the place without the Sims 2. But I do have ideas.

I am thinking about doing a Royal Kingdom Challenge, but with my own twist. Because I don't like downloading things, I figured I could do the challenge in the future instead of the past, with Aliens as the royals and nobles and some humans as merchants and only humans as peasants (or in this case, slaves).
I made my own alien skin, so I don't have to fuss around with trying to get a guy pregnant by aliens and keeping the alien gene in the family, or using boolprop in CAS (My computer had a major malfunction when I used it before and the computer didn't work for almost three months. At that time, I didn't have the proper paint/colouring program to make skins for Sims.)

Most of the rules would be the same, but I might just make it so that I don't follow rules for scoring. I would mostly do it for the story (although I do tend to get frustrated with stories) or just to play and post what progress I have made.
The story would go something like: Aliens have taken over the planet and enslaved the human race. Their superior technology kept the humans from revolting for this long. One town is at the center of the story. This town is where the Alien Prince, (whatever his name is), has decided the royal capital of Earth, Rivalen (as named after his mother, oh how sweet) to be. His generals, and others from (whatever planet name they come from) acquired slaves (humans, oh no!) and settled. Prince (whatever his name is) is determined to build a strong and lasting bloodline and town.
But, alas, there is competition afoot. His distant cousin (So and so), second to the throne should Prince (whatever his name is) suddenly find himself in peril and ultimately, death, decides that since he is of royal blood he should be able to make a royal city as well. Oendal, he calls it, after his mother (as is custom, apparently). With people loyal to him and their slaves (what fate for the human race, eh?) they make a rivaling city. Cousin (so and so) is also determined to create a strong and lasting generation line whom he will personally instill the hate of all inhabitants of Rivalen.

So I think I will do a little bit more for the storyline and then start up the game (since all I really have is time).
