Right now every option leads to the next option. Doesnt matter what you pick. Story only ends when OP gets tired of it.
The Barbarian will respond to this, because it raises a pertinent point. Each choice bears a fairly significant set of consequences. There are options that can lead to the End Game. In this very juncture, one of the three choices available leaves the voting body about two steps away from 'the End', and one away from outright defeat. Colloquially, Conan has labeled such options 'Bad Ideas'.
Though the Barbarian is loathe to kill off the game with a 'bad' choice, or two - especially this early - such is the nature of choice and consequence. Later on, there will be a natural end to the proceedings, and an epilogue.
Bottom line:
Yes, there are choices that will End the game. There is a structure.
Characters (at least, recurring characters) will not be introduced. Grand space opera takes place over proverbial epochs, rather than moments in time. However, the Barbarian would claim that Codexia itself is the 'player character'. One that your decisions have, and will continue to shape.

War Pigs
The General Staff of the Codexian Armed Forces took days to reach a decision, in that infamous meeting. By its end, punches and shoes had been thrown, shirts had been torn and tears had been shed. Not all were convinced that it would work, to put it mildly. Finally, Grand Admiral Laclong Quan and Field Marshal Angthoron made their presentation to the World State's Consul and, thereafter, the Senate. Codexia was to undergo total mobilization, and to undertake a strategic build-up of forces with which to crush the Raumen. The people, of course, were less than amused when the twelve hour workday was introduced for industrial laborers, machinists, technicians and all other essential service specialists. They became outright hostile when it became apparent that the new strategy would not yield immediate results.
Meanwhile, word of heavy civilian losses continued to pour in. First Jack's World, then Neo-Codexia were raided and sacked by alien forces. Physical descriptions of the Raumen became available for the first time. Spindly, four-legged blue insectoids with complex, delicate manipulators. This was the bug-eyed face of the enemy. Codexian troops, fighting with fervor borne of the arachnoid response, had some success during the vicious ground combat. There was some good news, amidst the bad, at least. And the bad got worse, before it got better. While the Strategic Reserve was forming up over the first six months of 154AU, the Regular Fleet was decimated - whittled away by fighting in the outer reaches of the Colonial Expanse; protecting every colonial possession as best it could, and suffering ghastly casualties, in return. And the Raumen, for their part, were getting cockier, readier to stick around after a fight. Public morale plummeted. The economy wilted under the immense pressures exerted by the war. Codexia approached the brink.
Oh, to be sure, there were isolated victories, here and there. Necessity had always been the mother of invention, and the Codexians were no slouches. The Regular Fleet and its Ships-of-the-Line mustered every technical resource in evening the odds. The Raumen were by no means invincible. Although the 'exchange rate' remained painful, the men and women of Codexia destroyed an increasing number of their sleek, green vessels. Salvaging them proved largely useless; nuclear detonations seldom left an intact superstructure, and the Raumen often came looking for the broken husks of their losses. The materials that were being recovered might have borne fruit down the line, but there was no time. Never enough time. The savage fighting continued without respite.
For the General Staff, the war was becoming an exercise in watching casualty reports with gritted teeth, and keeping a vigilant eye on the rapidly expanding Reserve. It was becoming a mighty force. Soon, thereafter, it was deemed ready for offensive action. The first targets of the Grand Counter-Offensive were selected. Timetables were established. Crews were readied, and families were informed of what awaited their loved ones in uniform.
The attack was launched on 7 August 154AU. Two major Raumen bases were selected for the honor of receiving the long-awaited Codexian riposte. And it was a thing of beauty, it was. The bugs were taken by complete surprise. The strategic mobility of wyrmhole travel was something they understood - but in no way were they prepared for the scale and force of the Codexian counter-offensive. Hundreds of ships participated in those first jumps. Though scores would find their destruction on the other end of the journey, it was to be considered a heroic sacrifice in a glorious victory. The Battles of Proxima Centauri-B and Cerces Star were to be recorded as the first major Codexian victories of the war. The Raumen losses were both catastrophic, and well cataloged.
Morale received the shot in the arm it had needed for more than a year.
For the first time, Codexians could speak of possible victory.
Do you... press on with the Counter-Offensive and attempt to smash the insectoid threat decisively?
OR
Do you... try to communicate with these creatures from a position of strength?
OR
Do you... dig in, replace your losses and gird yourselves for the next phase of the war effort?
