You have to look at this from another angle. While we were fighting the aliens in Prophecy, another alien fleet was establishing an alien wormhole in Proxima, only two jumps away from Sol. While you were busy trying to destroy the first wormhole the Nephilim had already set up a new one, much closer to Earth, without anyone knowing about it.
In FS, the Shivans (the bad guys in the game for those unfamilier with it) had far superior techonology and it was a struggle to take out even one of thier fighters.
Not after you got the shielding technology and new weapons.
The gameplay actually made you feel like you were facing a superior force.
For the first few missions after meeting them... Then, when you got the new tech it was rather easy. The only Shivan fighter that ever gave me any trouble was the Dragon, while others, especially bombers were far too easy.
