OK, last one. Unlike Colonists which have clear, powerful option, and unlike Spacecraft which has lots of similar but not that powerful options, Cargo has several nice choices (but I still think we'll get a clear winner). Hydroponics - extra Pop is always good, although this one might be better in the Colonist option for Refugees Laboratory - a free tech is also always good. Unfortunately the buildings it gives are useless at first as you have no one to trade with.... Raw Materials - Again, a free building is good, but +1 Science isn't much, and +1 health is pointless when you start healthy, and you have a long way to go before health starts being a minor annoyance Weapon Arsenal - Since aliens are so passive, and since the inherent strength of cities is so powerful, troops are pretty useless except for exploration at the beginning Machinery - Since the first thing you build in almost every Civ game, ever, is a worker, getting a free one to start with seems like an absolute no brainer to me.
