Additionally, Alphabet grants you the ability to build libraries (build this ASAP as it gives you x2 science in that city), Writing gives you a free spy, and the ability to build them, and reaching Literacy first gives you +1 science in each city. This will put you towards the front of the tech race and directly leads to mathematics (being able to make catapults-handy!). Choose Alphabet>Writing>Literacy if you want to focus on science development.However ,make sure you can reach masonry and irrigation first as the give you a free wall (+100% city defense) and +1 pop in each city.

(ex: being the first to research gunpowder would grant you a rifleman unit in your capital city.) After a few turns a message will pop up asking you what to research next. Many techs grant you a bonus for being the first to research them, this bonus may include gold, culture or science bonuses for your cities, even Great People! Being the first to discover a military oriented technology will always grant you one free unit of that technology. This forces enemies to attack across a river and also up a hill! (-50% attack for them, +50% defense for you!)

An optimal city location would be a hill surrounded on multiple sides by rivers. However settling next to a hill gives the enemies a +50% attack bonus when attacking from that hill. However settling on a hill is very good, as it gives your city a much improved line of sight and adds a whooping +50% attack and defensive bonus to units stationed inside.
