America - Now France has changed, these are some of the best REXers about. Then go to war after that.
Shoshone - Even better REXers.
Iroquois - Meh, could be ok with the right land, the UB is fairly early and gets decent production without requiring massive pop.
Aztecs - Not really; the UA and UB especially say tall.
Maya - Absolutely built for Wide, can probably still do ICS even in BNW. UB is a beast.
Inca - Hmm, more naturally tall, but have passable benefits for wide if the land is right. UA is very useful for gold, infrastructure and war, and the UI lets you work more hammer tiles for the pop you have.
Brazil - Haven't played them, but they seem more set up for tall.
Celts - Yes wide is good. There's synergy with the religious bias, and the later K-Lee hall is very strong when it comes.
English - Domination civ, it all depends on the land you get before your time in the sun. There are benefits for wide though, with fast movement for settlers, workers and army in water allowing for more spread out cities.
Sweden - Hmm, seem better tall.
Russia - Wide is fine, the UA is better this way, and the UB bonus can actually be useful going wide with BNW culture mechanics.
Germany - Domination civ, whatever is best for the land.
France - No longer so good going wide
.
Spain - Wide should be good, liberty will help get those NW's.
Portugal - Haven't played yet.
Dutch - Still one of the best REXers, and a wide strategy will help you get more of the flood plains/marshes that may not be next to your capital. Good wide civ.
Venice - Lolol.
Rome - Wide is good, UA will work well, and the UU period is a naturally aggressive one for wide civs anyway.
Austria - never played them; don't like the look of the UA.
Poland - Sure, why not, they're super powerful however you cut it.
Huns - Why build cities?
Mongols - Why build cities?
Persia - A civ built for a puppet empire. Does this count as wide?
Byzantium - Depends on the religion makeup, but wide is generally good, as it is easier to found a religion, and quicker to spread.
Greece - No obvious bonuses to tall or wide. Whatever's better for the land when you've finished carving your empire early.
Ottomans - Domination civ; whatever's better for the land.
Assyria - Why build cities?
Arabia - Absolutely built for wide. Do it.
Babylon - Probably better tall, but strong either way.
Carthage - Absolutely made for wide. Get the wheel, MoG and a tonne of coastal cities.
Egypt - Passable wide; the UB is good and good synergy as religion is important for wide, but give up a bit on the UA.
Ethiopia - The stele is good, but I like to go to 4 cities quick as possible with tradition then stay there; The biggest benefit of the stele is to get your religion first, not to pump out the 8th faith bought GS.
Askia - Domination, but tall is a little better than wide, as the extra gold means buying the settlers is still a decent option for these guys.
Zulu - Why build cities?
India - wide AND tall can work, but it won't be as early as other civs, which will require war. Luckily the UU is very good, even if the upgrade path is more than lousy.
China - Domination civ, though early game the UB makes wide a good start.
Siam - No, tall is better.
Indonesia - Wide is good, but ICS isn't once you've maxed your UA. The Candi is fun but probs not worth the science hit for that alone.
Polynesia - Wide is good; fun UA, and late game moai spamming is very fun too
.
Japan - Domination civ, whatever is better with the land.
Korea - Tall is more natural, but the wide specialist heavy strategy still works just fine for me.
Right, Who'd I miss?
