That force thing is hogwash. Both galaxies each with the same rules. Your Star Wars numbers are way off. Just play a Star Wars game like rogue squadron and you know the empire alone daily created thousands of ships not to mention private or planetary productions. Trillions of units? First of all many of the armies you speak of are not at that strength in the games and not relevant to this. Second ships in star wars are on average much larger than topical halo aircraft making your firepower display somewhat underwhelming. To be honest though im more of a halo 1,2,3 player so I might not be giving prometheans enough credit.
