Story Ideas

I got a few story ideas, all of which take place in an Equestria advanced by alien technology.

Problem for me being: which one to start with?

So here are the ideas:

-An anthology involving the Mane Six's families having their lives changed by accidents and/or incidents brought on by the alien tech

-A stallion stranger has to take down an upcoming warlord who has discovered a dark secret from the alien tech

-A stallion stranger works for Twilight Sparkle as the live-in mechanic and gets caught up in her shenanigans.
