CV T90
Game felt like a Prince game, for the sole exception that the AIs had gold like a normal Deity game (thus making it easier). In this game, I used Reliquaries with heroic relics.
Governors
I used the early Secret Society governor on Amani and I levied Valetta's units to scout the map and figure out the best locations to settle for monopolies.
Next, I went with Magnus/Provision
Heroes
I discovered a lot heroes early through scouting and meeting city-states.
First, I picked Sinbad which is obviously the best option to open. However, I had already scouted so much of the map that I didn't discover any continent/natural wonder with him. I only got 2500gold from him (7 charges used at 300g per in ancient era & 1 charge used at 400g per in the classical era) which is still not too shabby.
Second, I went with Hercules to insta-build 3 Holy Sites.
Third, I picked Himiko mainly to get envoys in Johannesburg so that they would acquire the luxuries I needed in their 2nd ring.
Next, I picked whatever was left. Unfortunately, Anansi was already taken before I discovered him. I also picked Maui who gave me 2 jades.
Tourism
Bought 1 relic from Genghis Khan
Bought 1 heroic relic from Wilhelmina (Anansi)
Bought 1 heroic relic from Lady Six Sky (Sun Wukong)
Bought 1 GWoW from Pedro
5 heroic relics from my own heroes (Sinbad, Hercules, Himiko, Maui & Oya)
8 religious tourism from holy city
Total: 160T
Monopolies
At first, I thought settling my capital on the Sugar near Valletta was a mistake (as I thought it wouldn't count toward the monopoly, but it ultimately did). However, you do need to improve 2 of them before you can get an industry.
I also sent builders in city-states' territories to improve them, but as I found later, it is a waste as even unimproved luxuries seem to count toward your total even if they are not improved.
Toward the end, I held four 100% monopolies (tea, dyes, gypsum & sugar) each with five nodes for a total monopoly tourism modifier of 420%
Zombies
I didn't play many games with them enabled, but they were slightly annoying in this game (ie doing their job).
There were quite a few in the area of Johannesburg. I had to hire a few units from barbarian camps, but it was not a problem since I was swimming in gold (combined with the extremely generous discount they offer).
Recent patch changes
Recently, tourism from heroic relics was dropped from 10 to 6 and the monopoly percentage per node was reduced from 5% to 3% in an attempt, I presume, to reduce the ridiculously quick culture victories with the Monopolies & Corporations and the Heroes & Legends game modes. However, as this game demonstrates these changes are not nearly enough. The way the monopoly tourism modifier is calculated totally needs to be changed. Even nerfing it further to 1% using the same formula wouldn't even be enough in my opinion.
SInbad.... the main man... I got him as my 9th Hero, it would have been nicer to get him earlier, in fact I got him with a project. Send him to explore and destroy ships ... and barb camps. (400 gold for half a ship vs 300 for a barb camp.... so 2 ships = 1600 gold. I found 2 continents and 3 wonders with him for 2500 gold as well. This was enough gold to buy all my settlers very early which is vital.
If you're doing a replay (and have perfect map knowledge), you can abuse Sinbad more than that:
you can wait to scout any other continent (3) (1500g)
you can wait to scout any natural wonder visible from water (4 on this map) (2000g)
use your charges against barbarian ships/camps (8 * 300 in ancient era) (2400g)
for a total of 5900g
When you get a Hero, send it off to get killed ASAP, I used Zanzibar which was a pain as heroes speeds are not increase with mathematics or the great lighthouse. I should have used Valetta... that realy does speed things up. So I got Sinbad built first but I erally should have built him in a low chop city as he is so cheap, instead I used my capital. After that I got Hercules to get 3 harbours up quickly and 2 charges of Anansi to get to Feudalism... but other than that sacrifice against barbs/CS ASAP for the relics... every turn counts.
At first, I thought the developers had fixed the hero deletion "trick/exploit" since I didn't see that option. So I suicided Hercules against Nalanda's walls and Sinbad against barbarians. However, later when I recruited another hero I found out that the delete option was still available and I remembered that a unit needs to be at full health for that option to be available. So yeah, deleting a hero right after you get it is the fastest way to get their relic obviously.
