Not to complicate things... but it would be interesting to see other races, in effect not just the Thoraxians, the Burlusts and the Peltians end up as conquerors of the system.
Perhaps there could be 'events' inserted into the flow of history, where the acquisition of space faring tech has a possibility of backfiring and blowing up a large section of the planet and the planets population. This could be temporary, or permanent. Permanent might be interesting as it could change the 'landscape' of a game from instance to instance (from game to game).
In this way, by chance some races will fail, and others will come to the fore.
What this could also mean, is that even with all our efforts to get a race to space faring status, our efforts could come to naught. An interesting possibility which makes the process of helping them a doubtful thing. Also interesting because it is possible to produce a different outcome each time we try to bring a race to space faring status.
Or you might have other things in place already, but just thought i would throw an idea out to see what you thought, hope you don't mind.

Just a quick amendment.
Looking at this now makes me wonder if it doesn't seem sort of over much to have this happen on a 'regular' basis. I mean the possibility 50% every time a race tries to go space faring, might be way too much.
To be fair and to put it in a 'proper' light (one with less chance of happening all the time), it might be better to pare this possibility of failure during the try to reach space fairing status back to a 10% chance of happening. So it will happen, but much less frequently.
And as Chris mentioned there will be the possibility of 'other' things coming into play that effect that event. Like several races banding together to reach space fairing status together, or banding together into a mutual group to fend off the larger or more advanced or hostile races.
So we could have several kinds of empires or federations, Our Federation of Peace, The Federation of Fear, but also the Federation of Mutual Interests?
Each type of Federation could be permanent on forming, or as in real life, subject to the forces of the universe around them. Perhaps forming and then a hundred years later collapsing from internal disinterest, or opposing agendas of the member parties.
There could be other 'events' of course just as viable as the groups of races banding together for self protection. Such as random meteor showers that destroy armadas, or planets. Thereby eliminating some participants accidentally. Which may make things interesting in that it may make us realize that the workings of the universe around the player and the other races is just as deadly, and game altering, as their skirmishes and wars and political maneuvering.
Just some thoughts, hope this all is OK. You've probably already thought of all this stuff, but it is just occurring to me, so it all seems new.
Thanks for listening,
