It wont let me take a turn?
In my original concept, people could all take turns simultaneously, but hottest forces players to go person-by-person. This will slow us down. CPM was JUST online when my turn started, but then stopped playing Tropica and left. I'm sure you'll all get through a turn tomorrow. At least, I hope.
On a worldbuilding note (this applies to you redwings!): don't think of your civs and cultures yet. When I wrote my first two paragraphs, Madrid was a China-like isolated country of insect-paste eaters, but in the next they were an underground whale-singing settlement. It really varies. And even though my UA should play into my civ, the lore behind the UA will only be developed as it appears. This example may not work for some other civs with restrictive playstyles, but just know that everything is really open for the first while. I can just as easily see Persia as a mason-working deer-pickling forest community as I can see it as a plantation monopoly on a river delta. A lot of stuff can happen.
Also, when the game starts, the only major tech you have us agriculture. So just think about how the will relate to your civ. You still WORK two tiles during your first round, but you don't have improvements on them such as quarries or farms. In past playthroughs, I made unimproved but worked tiles become a less sophiscated or populated industry. If I was working a fish tile, but I had not yet discovered sailing, I'd make the fishermen be coastal-based, using nets and floating out on driftwood, perhaps.
Or, if I began working a furs tile after animal husbandry but before trapping, I'd have to make the tile yields relate with the technology. For this example, furs provide 1 food, hammer, and two gold. Perhaps the foxes and dogs are being bred and sold as animals, causing an influx of gold to that community. Dogs also help around the nearby sheep-filled hills, increasing productivity. However, it is in poor judgement to eat a pet, therefore lowering the amount of food being able to be hauled away from the fox-ridden forest.
These are just a few examples. I have a bunch more, tell me if you need anything. Read stuff on stuff as well if you have time.
Did you know geometry was developed in Egypt to correctly divvy up the fertile delta lands?
Also, a steep, fast running river usually erodes the land when it exits, creating a fjord or inlet. A slow moving, sometimes winding river will create a delta, with silt deposits. After exploring, decide what your nearby rivers are. If you don't spawn next to a river, best of luck.
