Longterm save - career game, what shall i load?

for the longetivity of the game and plenty of good solid regens for the future, what leagues shall i load and what players shall i load?

im doing leagues wise: france/eng/germany/spain/holland... thinking about portugal over holland maybe. anyway, i need advice please on which players from what country because ive read that if you do this, it preserves the longetivity cos more good players are made = clubs become stronger.

Wales .. Definatly .. I am Neath FC and it is soo much fun .. Trying to win the CL

Try leagues where you have never managed before, that is what i have done.

Argentia and Brazil are good to have loaded, plenty of good players appear there, and if you want to be able to use them without work permits then Holland and Germany , though really its where ever you fancy with maybe the big EU countries included incase you want to manage big in the future.

so which leagues shall i load? its pretty intensive on my system because its an LLM save. i don't know whether my PC can take more leagues (3.0ggz quad core).

and which countries shall i load all players from?

load all players from brazil and argentina, they're quite cheap and fairly good. as far as the rest, load all possible nations in europe. EN, FR, ES, GE, IT, PT, HL, RU, UKR, etc.

thanks. so if i load all players from possible nations, will i get more regens from them? or do i have to have their leagues active? interested in how it works, thanks.
