I'm cutting a bit more out of Tin, but keep in mind a lot of Tin and a lot of the northern nations is useless tundra, whereas you're near the equator and have a much higher percentage of usable land.
I'd like to all be friends here and not get too heated, but I'm actually rather pissed that you cut swathes of Tin out, in spite of the fact that the borders previously made sense geographically (following mountains and rivers) and that I'd already drawn my own relatively detailed map and how my sheet talked about how the northern riverlands and southwestern mountains were important economically (both features seem to have been taken), and now all that will be redone. To boot you didn't even ask me.
As in for the neighbors having mostly useless tundra, even if we assume that's true (which I could argue against) they chose that land and didn't object when I plopped down Tin to the south. You're also ignoring the fact that I probably have the smallest ratio of usable land of anybody. Half my land is desert and plenty more is mountainous, which is good for mining but not much else. Incidentally, what grassland, riverland, and mountains that I had were what was was taken out.
With 125 million people I'm about in the middle for population. I don't have any special materials and I have the worst technology and industrialization out of all nations so far, and when I make my military section you'll see that my navy is just decent, my army mediocre at best, and my air force almost nonexistent. I did all of this just because I wanted to be the Russia-blob across the landscape. That was all I wanted, about all that made Tin stand out, but now it's actually looking like there might be a few nations that are actually bigger than me.
So needless to say I'm annoyed and disappointed by these changes to the map.
