Anyone have thoughts on the best fast-guardian kill race?
One of the challenges is avoiding being spy-raped for all the techs. This makes a traditional fast-techer like DemoLith more than slightly foolhardy. You can do it with a race like that, but you might have to pray you DON'T get XArmor, because once the AI has XArmor Loknar is not nearly as effective.
I tend to think that the best options are Aqua/Creative or Aqua/Unified, with the remaining stuff being research boosts... LHW+AHW is always a good start.
Not the best research races, but offering a balanced approach without a spy penalty.
Production races are the fastest. They can expanded quickly and can build more research buildings in less time. The best of the production races is unification, tolerant and production+1, large hw, repulsive, -20 ship defense, -10 ground. Unifiction is +50% food and production, and no moral penalty. It also gives +15 spy defense. Tolerant increases the population limit because it treats all worlds as terran, and it elminates having to worry about pollution. Production+1 has good synergy with tolerant and unification. Another good one us unification, aquatic, lrhw and prod+2.
