So, I tried to make a feedback to your latest preposition to the RS. Am I happy with it? No. There are points to which I'm sure, but many changes have vague motives and many other different divisions are possible.
The coast locations are OK. They are the same in my early map.
My main critic is that you're map does not represent the elevation in the northeast. This is by far the main(and mostly the only) terrain feature of the region. So I made the following changes:
- increased the wasteland northwest of Osório, based on Sulphurologist's TRI map.
- Removed the location of Santo Antônio da Patrulha, as it contained flat lowlands, harsh hills and flat highlands in the same location. Going from Osório or Porto Alegre to Vacaria you must pass through rough terrain.
- The lowland part of Santo Antônio da Patrulha was annex to Porto Alegre. The highlands part was made into it's own location named São Francisco de Paula. The rough middle part was too small to be a single location so was annex into a "new" location named Caxias do Sul.
-The location of São Leopoldo had the same problem. It's lowlands were annex into Porto Alegre or São Jerônimo. The small highland was annex into São Francisco de Paula and the rest became Caxias do Sul, as the city of São Leopoldo is actually in the lowlands, now part of the location of Porto Alegre.
This way, the lowlands locations -Porto Alegre and São Jerônimo- and the highlands locations -São Francisco de Paula and Vacaria- can be flatland while the location of Caxias do Sul can be hills.
Small redraw the border of Vacaria and Lagoa Vermelha:
- Northwest of Vacaria was expanded to include all of today municipality of Vacaria.
- In exchange I continued the border following the frontier of the Vacaria municipality and added some terrain to southeast Lagoa Vermelha.
This cut the connection between Vacaria and Caxias do Sul and I don't dislike it.
Small change to Soledade borders, added some terrain south where is hilly and removed some terrain in the northeast where it is flat. This way the location is a little more homogeneous as a hills location. Also removed the horrible south tip caused by the municipality of Agudo.
Expanded the Passo Fundo westwards till the line of the San Idelfonso Treaty. It became kinda huge location, so I split it into two, with a northern part that can be classified as hilly and the proper Passo Fundo location that is flatland. I named the north location as Erechim, as it's the biggest city there today.
The reductions region had some big changes. I'm really not sure about my idea, but I prefer it to your map because you grouped all seven reductions into only two locations and it does not follow the San Idelfonso treay line.
- Firstly I cut the location of São Borja in half. The southern part of São Borja annex part of Itaqui location. The northen part contains three other Jesuit missions and was named São Nicolau.
- The north border of this location of São Nicolau was changed to meet the Ijui river. This river futher divides the mission of Santo Angelo to the north and the others to the south. The river basin goes east to the line of the treaty of San Idelfonso.
- At this point a space remained north of the Ijui river and west of the treaty line. In this space, next to the river, there is the reduction of Santo Angelo. I decided against keeping it a single location as the colonization of Santo Angelo came not directly from the Argentinan lands in the northwest but from the other reductions in the southwest, across the river. Therefore, I found that having the location of Santo Angelo bordering Argentina sounded weird. I then cut it in half. I'm not sure about this solution. The new northwest location can be named Santa Rosa, as it's the biggest city today.
- The other reductions south of the Ijui river and in the old location of Cruz Alta were reorganized into a new location with the treaty line as the eastern border. To the south I annex parts of the Itaqui and Santa Maria locations.
- The Santa Maria and Cruz Alta locations were cut by the treaty line. Their eastern parts were fused into a single location. This could be named Salto do Jacuí.
- The remains of the locations of Santa Maria and Itaqui were grouped and annexed the northern part of São Gabriel to make a new location, named São Vicente or Jaguari.
The region west of the Madrid treaty line was mostly unchanged. The Bagé location was cut by the San Idelfonso treaty. The eastern part I annex to the Jaguarão location. The western part was made into a new location with the eastern part of the Santana do Livramento location. I kept the name Bagé, as the today city is in this location. I don't like the shape of this location.
The weird space between both treaties was organized into a new location. It's weird and impossible to find a good name. I'm not convinced of neither this location neither the new Bagé location.
The remains of Santa Maria and São Gabriel east of the San Ildefonso treaty line were annexed into the location of Cachoeira do sul and the remains of the location of Caçapava. The names Cacheira do Sul and Caçapava do Sul can be kept. I also changed a little the border between this two locations so that Cachoeira only has the river flatlands and Caçapava has more parts of the Escudo Rio Grandense.
The Provinces were designed conidering the colonization timeline, as the colonization mecanics is by province.
This changes increased the number of locations back to 30. I don't think it's a problem.
Some feedback about names:
- Osório should be Conceição do Arroio, as it was this name before 1930.
- Porto Alegre should be Porto dos Casais or even maybe Viamão.
- São Jerônimo should be Tiunfo or Bom Jesus do Triunfo, as it is the older city in the location. São Jerônimo was created from Triunfo in 1938.
- Caxias do Sul is completely ahistorical (named after the duke of Caxias of the 19th century), but I haven't found a better name. It was very late colonization.
- Santana do Livramento is officially Sant'Ana do Livramento.
