Let's see:
- The UA is best exploited by running enough cities maxed out on Scientists to have each city produce a GS before the game ends. For Space, you need about 15 cities and Universities to achieve peak UA efficiency. For a Diplomatic win, you can lean more heavily on early Research Agreements, run fewer cities, build fast Libraries and worry less about Unis.
- The UA also lets you produce Great Scientists for early bulbs. Using two Libraries and the free GS, you can have three Great Scientists by the time other civs can have one. There are plenty of fun things you can do with this:
- One option with Rifle rush is to use the free GS and produce two more. That lets you bulb Steel, Physics and Gunpowder to open Renaissance very, very early. If you buy a Cultural ally soon enough, you can deploy Rifles starting around turn 90.
- Another option is to aggressively get to Renaissance bulbing Theology, Education and Acoustics. A more useful approach on Continents is to bulb Compass, Education and Astronomy.
- A third approach is to beeline Writing from the start and build an Academy. This will get you fewer Science points than bulbing deep, but will permit you to open the early techs much faster (since it essentially doubles your tech production in the very early phases of the game). Depending on your start, this can provide a stronger result than a series of deep bulbs. It is particularly helpful if you want to Iron rush but also need a lot of techs to hook up luxuries.
