Beat a small universe custom game, with all 9 opponents on Suicidal difficulty. First being very peaceful, trading tech with the others in order to try and keep up with their absurd technological research speeds. Then, I lashed out, crushing the Thalan with a surprise attack, leaving most of their military on the other side of the map fighting another war. Turned all other factions against the Yor, who was dominated their side of the map (they were defeated by 6 factions working against them). Traded the victor's of the Yor war for their new planets really cheaply. Then slowly grew in power, crushing those that declared war on me, since my influence was slowly conquering the galaxy.
Influence win was disabled, so eventually I obtained every single planet, save for Drath's homeworld. (They built a re-education center). Researched every single technology, then won with Technological victory.
