Conquest envisions a universe in which it's every race for themselves, and, instead of working overtime to reintroduce peace, Captain Picard falls right in line and tries to take over all the worlds too. The Galactic Federation, a utopian union of races and planets working together to form a more perfect universe, now embraces war machines, which they fuel by strip-mining resources from planets they conquer and enslave.
Leading your fearless, battle-thirsty savages is the cry, "This is for Earth!" because Earth is suddenly the only member of the Federation that matters. They might as well play "The Star-Spangled Banner" for the victory music.
Planet Earth, fuck yeah!
Remember the Genesis Device? It's Star Trek's version of a WMD: considered a failed experiment because, though it will introduce life to a barren world, it will also kill anything on an inhabited one and replace it with its very own "life matrix." Yet Conquest not only embraces the Genesis Device as a first-strike weapon against non-Earthlings, it throws near-unlimited Devices your way, allowing you to rain genocide on every planet you come across. This not only negates the morals of the show but also the whole "strategy" element of this strategy game.
In an Easter egg, you weep, for there are no worlds left to conquer.
