Greetings, Hydral. I will be your computer for this "grand strategy campaign with turn-based tactical combat." I think that's code for "we're going to die."
Our solar system is vast and complicated, and I sense you are a little dimwitted -- so I tell you what, let's start with the simple stuff. Like escaping with this flagship you just hijacked from a bunch of angry robots. That seems important.
Please excuse my impertinence, but I believe you are the last of a murdered race, yes? My records note you Hydrals were the dictators of the solar system, so basically you had it coming. And by "it," I mean the moon that smacked into your homeworld. Hmm. So people really aren't going to like you until they get to know you. Well, only you can use the scattered remnants of advanced Hydral technology, so that's something.
Look, I'm not going to tell you what to do. My understanding is that you're trying to form the solar system's first-and-last unified federation, and that's noble enough. But right now nobody wants that except you, and you've got 8 very diverse, very angry races to either unify or exterminate. So... good luck with that. I'll help how I can.
