Sooo. The start position is defined
here, and we lucky Conquest class players will have seven units on a tile in the middle of a floodplain, including two settlers, two workers and three treasure chests with wobbly wheels.
I haven't seen any new thoughts on the effect on our start, so here's my 2 Euro cents worth on how the Conquest class extras might come into play at the start:
We need some shield-producing tiles to complement all that food production, so a bit of exploration wiil be needed before settling down. Based on the information we have, population growth is going to be easier than shield production, though there are likely to be some bonus tiles about. I've tried a couple of Deity practice starts, and one of them was in a flood plain. I lost two pop points to disease before the capital reached size 4. That was forty food and twenty shields written off, so that extra food also comes at a price.
I think I'll found two cities as soon as possible, rather than join both settlers to one city. It will give us two chances to find a decent settler farm location, and provide some backup against getting hit by disease. If the positions are good then they'll get us off to a good population start.
The treasure chests will help to offset possible low early shield production - they'll provide welcome shields for a cheap but powerful fortress in each town, and maybe a head start on a temple in the second city to grab territory. In my practices the AI expanded terrifyingly fast. I'm also guessing the Romans might not be far away given RL Spanish history, so good defences could be needed against Legions as well as barbs.
A Treasure chest moving along with a settler to scout just ahead in the current turn looks like a great idea. Thanks SirPleb. By keeping close to the settler they can quickly disband in the city once it's founded, and you are less likely to waste valuable worker turns on scouting trips up hills.
The hill to the north east looks like one possible city site. Maybe I'll send a treasure chest up the hill on the first turn to take a look.
The western hill looks like it has coast on two sides, although that could be fresh water, of course. Depending on what the first scouting chest finds I would be tempted to send a second treasure chest south to see what happens to the flood plains in that direction. There look to be a couple more flood plain tiles, and one with a wheat bonus would give a great boost to a settler farm, freeing up a citizen to work any shield tile we can find.
On the assumption that we'll have to create one or both cities close to the start, we could get the two workers pulling together on irrigation right away on the start tile unless we see a better tile to work. Alternatively work two adjacent tiles to get the road network going between the twin cities.
Anyone else had any more thoughts since seeing the start position?
*grin*. I`ll use this as an encouragement to go through another bloodlust this GOTM :die: . Also, I really have won sometimes in deity. Mostly as Egypt, Aztec or Japan. I`ll play a training game Spain later.
