It'd be nice if you could just tell OOTP to produce players from an entire region or world with X% being from BBQUAL 5 nations (at full value), and Y% being BBQUAL 4 nations (at .95 value), etc. You can't do that, and OOTP doesn't seem to devote a lot of attention to this part of the game, so I'm not holding my breath.

Within a particular region, however, OOTP does fine distributing talent by population.

So the simplest solution would be to create 4 leagues (assuming you are going ignore level 1 countries like I did), or sets of leagues, each one based in a region that is determined by BBQUAL level. Bonus! These regions already exist in the game! You don't even need to create them.

That approach gives two choices neither of which appealed to me. You can base the league in (say) the United States and have the talent drawn for the particular BBQUAL nations. That loses a lot of local flavor, although it's easy to image it. Afterall, it's basically what happens now. If you are good enough baseball player to get paid for doing it, and you don't live in Korea, Japan or Taiwan, you try to come to play the United States.

Alternatively, you can have teams based around the world. But it hard (for me) to suspend disbelief when you have teams jetting acorss the international dateline or equator to play each other. The logistics of all that just bother me too much. YMMV.

What I did was create 25 regional leagues based on geographic proximity AND BBQUAL:
BBQUAL 5 [272 teams - 69%] - player creation modifier 1
7 US leagues (168 teams total)
3 JP leagues (48 teams)
1 Caribbean league (32 teams) - CU, DR, PR, VE
1 CA league (24 teams)

BBQUAL 4 [52 teams - 13%] - player creation modifier .950
1 Caribbean league (24 teams) - MX, PA, NI, CR
1 KR league (10 teams)
1 TW league (6 teams)
1 NE league (6 teams) - includes Curacao
1 AU league (6 teams) - plays in winter

BBQUAL 3 [42 teams - 10%] - player creation modifier .850
1 European league (24 teams)
1 Asian league (10 teams) - includes Oceania countries
1 Carbbean league (4 teams) - CO, HN, SV, and a bunch of small islands
1 South African league (4 teams) - plays in winter

BBQUAL 2 [28 teams - 7%] - player creation modifier .750
1 European league (10 teams) - includes European Russia
1 Asian league (6 teams) - includes Asian Russia
1 African league (6 teams)
1 South American league (6 teams) - includes N. Am 2s, plays in winter

That seemed a reasonable distribution of players by level, although probably the 4s should have a few more teams. Within each level the players are distributed somewhate closely with the population of the underlying countries, except that I nerfed China in favor of Europe at level 3. China is one country whereas there are dozens in Europe, but maybe that is bias on my part as well. The China group does include a few smaller countries as well as China, so they are also getting nerfed, but they are so small compared to China's population that for all intents and purposes the BBQUAL 3 Asian league is just China.

So that was step 2, creating a distribution of talent among the countries roughly proportional to population and talent.
