Would it be alright if I play as an interstellar megacorp?
Basically I'd less of a civilization and more like a corporation of great number of companies that are present in at least hundreds of different civilizations.
I may be the largest shareholder in these corporations but my holdings would be subject to the local laws in general.
I'd only own a single planet which would be also the megacorp's headquarters.
As for tech it'd be technically a mish-mash of anything which can be traded for in the galaxy along with the company's own researches and improvements.

So yeah, basically a galaxy-wide megacorp which would trade with nearly anyone else.
Capitalism at its purest.

How would this megacorp be formed?

I mean, first, this megacorp would have to originate from somewhere- likely being a corporation within a pre-existing nation. When there is enough trust between multiple nations that have made contact with one another, then they would have to try and branch out to other nations, would could be taken as a sign of aggression, politically and economically. That, and nations would be uneasy with a foreign corporation sticking its nose in and buying up everything to sell it to everyone else- it could either greatly increase economy, or greatly hinder it, while giving the corporation significant power if it becomes successful, because then they'd have a large part of the economic system.

That, and you'd have to create some kind of UN to create either a galactic currency, or to agree on a currency exchange that is suitable for all involved parties.

A megacorp in the early contact-and-establishment part of the roleplay wouldn't be logical. Unless someone is foolishly trusting of others, then getting a foothold in other alien nations and integrating into their economy would be problematic and difficult, especially with nations that have only one race- they might be xenophobic on a whole.

This is, of course, what I think, not the truth or the word of law.
