Hapiness management

Happiness is one of most important resources in the game.
If you have enough, you can build/puppet more cities to get any other (except time of course).

Although it is global resource, its good to look at it per city. If city is negative, you must have another source of , if it is neutral, you can have unlimited ammount of these cities and if its positive, you can have unlimited amount of these cities and swim in golden ages/have negative cities.

Most important mechanics:
1)
Every city gives and every population gives .
On normal map size, its 3 per city and 1 per pop. On huge its 0.6*3=1.8 per city and 1 per pop.
And for Ghandi its 6/0.5 and 3.6/0.5. Lets concentrate on all other civs.

2)
Hapiness buildings output is limited by city size.
So for sizes 2,5,9 (and +1 and +3 for circus and stone) you have compensated per pop hapiness if you build hap. buildings. But per city penalty remains.

3) Policy based bonuses are not limited by city size, even if given through buildings.

This means, that if you have 3 policy hapiness bonuses per city and apropriate size and basic hap. buildings, you have neutral city.

Per pop bonuses are 5%(and +1 per city) in liberty tree and 10% forbidden city.
it gives one per 20 and 10 citizen.
There is also +1 per 10 citizen in single city in tradition tree.
Although it looks like 10% from forbidden pallace, this bonus is weaker, because 2 pop 5 cities does not gain anything from it, and 5 pop 12 gain only 5, not 6.

Annexed cities gives much more unhapiness, and if you build courthouse they revert to normal cities (with possible +3 hap on courthouse from SP). But bug in current version causes courthouse to eliminate per city unhapiness, which makes it too good, so I will not consider annexing spetial option.

Early game, there are 3 per city bonuses available.
1) liberty one that gives 5% pop bonus on top
2) honor one that gives +1 per city (and +2 culture) for garrisoned unit.
3) another honor policy that gives +1 per defensive structure (walls etc.)
With policy in tradition that make you not pay upkeep for garrisoned units, it is even more interesting, BUT your per unit upkeep increase even if you don't have to pay it, so other units in field are more expensive, thus it is not good idea to build much more units than you want to have when fighting.

By this time, only available hap. buildings are coloseum, circus and stoneworks. This means that on normal size map, you need 3 per city hap to have neutral size 2 (or with stone/circus/both 3/5/6) to have neutral city. Clearly, per pop bonus is not interesting here (for huge empire), because even pop 6 city gives only 0.3 hap = 4 such cities gives 1 (and .2). But it comes with +1 per city, which is the reason to take it. (And another point is, .95 unhapines is les than 1, so 5% bonus can give one whole hap. But this rouning error does not scale with number of cities.
How to get 3 per city?

all 3 policies (needs 7 sp, so definitely not early) gives 1(trade)+1(garrison)+1(walls) and possibly (+1 castle) (and later 2*+1 for other defensive buildings).

In later policies, there are +1 per univ/college/observatory (means +2, sometimes +3) and +1 per city. And +3 from courthouse, but CH is bugged, so using it gives unfair advantage.

This makes honor THE best hapiness policy (with 4+1(garrison)) effect, that overcomes per city penalty even without garrison.

And on larger map size, its clear that it gets easier for everyone and especialy for Ghandi.

Note about Ghandi: On normal map, cities with size<6 are worse, >6 better and 6 equal to other civs. This means that before theatre, ghandi have big disadvantage, but later can dominate (his cities are bigger = complete things faster).
and on Huge map, size 3 is worse and size 4 is already better than for other civs = on these sizes, ghandi have HUGE advantage, even for ICS.

Tradition: In addition to the pop 10 bonus, there's another policy that cuts half of unhappiness in the capital.

As to unit maintenance, my computer denounces Civ V on anything bigger than standard map, so there's really not a situation in which during a war you'd want fewer military units than you have cities in the games I play.

This does mean though that when at war, my maintenance costs shoot up as many units that were garrisoning have to be deployed onto the field.

The main liberty happiness is the +1 happy for a road connection. That +5% is much smaller; at least early on.

I think you've fully covered the honor happiness bonuses.

Piety: This comes a little later, but not much so. There's still a ton of ways to get happiness here, even more than there was before the patch.

Next are mid game:
Patronage still has one the boosts happiness from resources from city state allies.

Freedom still has happiness boost from specialists, only now you have to go thru several polices to reach it, including one that increases growth from specialists, so not as effective a happiness management tool as pre patch. (And it rules out Order as well.)

I think Commerce unlocks at the same time: +1 happiness for every luxury resource regardless of source if you go that route.

Rationalism might unlock then but could be later, but regardless if you go that route you get happiness from Universities.

Then there are the late game:

Order: +1 happiness per city just from the base policy. (If you've also gone Liberty, that means your down to only +1 city unhappiness)

Autocracy includes making Court Houses even larger sources of happiness.

Basically I think post June patch your supposed to decide what you want your empire to look like; and they'll be something happiness wise for you that's already included in what your doing.

I'd generally rather have +1 happy on my monuments/temples instead of walls/castles/garrisons. Arsenals/Military base come too late to really matter. Culture is always useful and monuments are generally the first buildng anyway, so you get the happiness earlier. You also get the boost to building production & extra culture if you go down piety, whereas you're forced to warmonger if you go down honor. Also building walls/castles in safe core cities is kinda wasteful if the city is never goingn to see combat (although there is no maintenance for those buildings, which is saying something). IMO going honor strictly for happiness is probably a bad move. Going honor for happiness AND warmonger benefits is great.

Honor without fighting is bad, I agree.
One nice thing about honor tree is, that it makes puppets with garrison produce 2 culture even before they build cultural buildings, so honor= warmongering + happiness + culture

Yep, it fits in quite nicely with puppets. They like to build walls too. Overall if you're warmongering/puppeting it's a very nice tree.
