Kind of OT, but I really need to know:
1. How do you REX with India's +6 unhappy per new city? It's a heavy cost at the start.
2. How does the happiness system prevent properly tall cities? Tall to me is about size 30-ish. Not tall enough?
there's only so many +happy available, so you're capped in a particular city by what you can build there and what SPs you've taken.
30 is decently tall, though outside of the Indians, it's hard to get there with a non-capital city.
an Indian REx doesn't start until you line up enough happiness to overcome the 6/city. You also need to be able to grow them to 12 pop each, which takes time. So you will be stuck with needing 3 lux/2 cities for some time. Settling choices early is fairly important. Once you get rolling though, you will just use lux's/other global happiness not listed below to 'manage' the happiness/city until the city hits 12 pop.
generally, you need to wait until Renaissance (at least) before really pushing it.
keeping in mind that your capital will only produce 1/4 unhappiness, that's only 3 for a 12 pop cap. you'd only need Aristocracy and a coliseum to handle that. (if you use the 9 default happy to cover the city. Else you'd need a bit more happiness)
Assuming a Tradition/Honour game since you 'might' build the UU Fort anyways.
coliseum + theatre = 5
aristocracy (new) = 1
garrison + wall/fort = 3
That's 9 you can easily do, so you just need 3 more from:
circus (2)
Stoneworks (1)
Organized Religion (2 for monument/temple; 3 if a monastary)
Professional army also adds +2 more for the Arsenal/Military base, but that's less useful.
Order (Industrial, but still +1)
Meritocracy (1 + 5% discount on total pop)
- it's a little odd trying for the -5% unhappiness with India. I'd have to test if it's additive or multiplicative.
toss in the FP and you get another 10% off.
Eventually you can grab mass media for the Stadiums, but that's more to add population to each of the cities.
