I am the G.M. of a Play-By-Post Sci Fi Game

Started in 2130 - now 2137

We have very fast FTL Drives - but we have encountered a very unpleasant Alien Species ( the 'Zetans' ) who are trying, so far successfully, to conquer the whole of this Galaxy ( the Milky Way ).  We seem to have stopped them for the moment.

We have rescued Friendly Aliens who they had ensalved - so four new Friendly Alien Peoples have joined us - ths was later increased to five,  We now have another Alien People as our Allies ( six ) - who we found on a planet where they were hiding, after near genocide by the Zetans.

We are gearing-up to hit the Zetans hard, in this long and slow War.

Humanity has discovered 25 Star Systems, which we have fully Scouted.  23 of these are in various stages of Colonisation - including some Star Systems which have a number of Habitable Planets, and some which have only Asteroid Belts ( we have large Colony Bases on Asteroids ).

In Sol -

We are Terraforming Mars, which is now some 90% completed, and Cities are being built there

We have started Terraforming Venus - Atmosphere, Hydrosphere, Rotation, and a new Moon.

Our Fleets of Interstellar Warships are very large - over 1,100 Ships now, from Destroyers at 500 metres long, to Superdreadnoughts at 45 Km long.

We have nearly finished building tow Super Battle Stations - 600 Km in diameter, a lot like "Death Stars".

Howver - the Zetans are technologically behind us - BUT they have so much more in theory.  Thousands of Planets, maybe Tens or even Hundreds of Thousands of Planets.  The Zetans are a "drone" Species like Ants - with a fairly central "hive mind" linked by Telepathy.

We are formed into a Confederation of semi-independent Dominions - each with their own Star Systems, under a central Democratic Government.  There is some competition between Dominions, but a lot of cooperation as well.
