I have not played it yet but will give it a go next week.
I always struggled in Civ where after seeing my surroundings I wished I was another race, this seems to tackle that. A bit worried about the length of combat in later Era's but time will tell.
I was wondering how well Aesthete's play? It certainly seems like they can vassal people easier and get a peace deal faster, apart from against militarists?
Aesthetes get extra Influence, and early in the game 'Influence' (Civ's 'Culture', sort of) is a very important and relatively rare Resource. It is the currency you use to place Outposts, upgrade them into Cities, and (with Money) 'bribe' Minor Factions into liking you enough that you can assimilate them or at least keep them from attacking you. This last can be very important, because, like the Barbarians in Civ, the Minor Factions play by very different rules - they don't need any Resources to build units, and they spawn units at a vastly faster rate than any Major Faction, which means while you are struggling to build your first Rider or Warriors, they are pumping out Heavy Chariots, Spearmen and Archers and (if they are 'violent' types) gleefully Ransacking your Outposts and playing Run Over the Speed Bump with your Scouts and Archers.
Vassaling Major Factions is less important until later in the game, because going to war is usually not a good early option for Aesthetes compared to rapid early expansion by peaceful means, at which they excel. In my (limited, admittedly) experience, keeping a reasonable army will deter the AI Major Factions from attacking you, at least early in the game, which leaves an adroit Aesthete player free to maximize the expansion possibilities - and if you manage to assimilate a Minor Faction early, you not only get another already-established City, but also a number of military units to augment your forces. The only problem with that (and brake on the temptation to use the new armies to conquer your Major Faction neighbors) is that if you don't have the Resources for the new units, you cannot 'repair' or recover them - any combat losses they take are permanent, so it is nearly impossible to sustain any offensive with them.
We are going to have a lot of fun in the next few months discovering all the possibilities of the different types of Factions in the game, and the possibilities of the combination of them: if you start the game as an Aesthete (Zhou and Olmecs are the Aesthete Factions available in Ancient Age, Mauryans in Classical) their Legacy Traits carry over into your later choices. That means, you can get the additional Influence (or, from the Zhou additional Stability, which is very important to keep cities expanding and productive) even while later playing a Merchant, Expansionist, Agrarian, Scientific or Militarist Factions. The combinations, I foresee, will spawn a host of "Playing X, then D, then Z, then Q is OP!" posts both here and over in the G2G forums . . .
