YEAAAAAHHHHHHHH
I'm going to go do something else for a few minutes, and then I'll write the ending cutscene thingy.
EDIT:
After a medium-length desert trek plowing through rocks and primitive water retaining autotrophic life-forms at speeds in excess of 60 miles per hour, the dozertank arrives at the only sign of civilization on this planet as the massive blue-white star that it orbits sets in the south. A group of human-looking people dressed in labcoats come out to meet you.
As you climb out of the dozertank, someone steps forward from the crowd and shakes your hand.
"Greetings, children of the planet "Earth". My name is Elerious Varrin, and I am the leader and head researcher of this outpost. You're probably wondering who you are and what you're doing here. I will explain. I believe most of your cultures consume alcohol, yes?"
You follow him inside and he pours each party member a large glass of a dark green liquid, then drinks the remaining contents of the bottle and tosses it into a recycling bin.
"You three are cloned specimens of
Homo Sapiens, grown
in vitro in this outpost's laboratory complex. We are an ancient race known as the "Stephinians", one of the oldest and by far the most technologically advanced species inhabiting the known universe. We are the closest thing to an universal government that exists. The experiment you just completed is one of a series of tests we are performing on your species to determine your "galactic societal acceptability", or in blunter terms, whether or not we should blow up your planet. Don't worry, we've only had to genocide a few hundred species during the several trillion years we've been doing this, and your species is giving decent enough results that we shouldn't have to take any drastic measures. That's about it really. Standard procedure dictates that we hand you a Duality-equipped starship (that refers to the sort of computer that runs the thing) and basically let you go out and cruise around space for the rest of your lives. Your ship should be ready any minute... so... Welcome to the galaxy."
