How do I start with the Gigantic (300,000) player database?

This is probably very obvious to most of you but I am wondering how you start a new career with all 300,000+ players? When I chose the large database I only have access to 83,000 players.

Apart from choosing large database, choose load all players from all 6 continents - you should have all the players from all the countries that way. Whether you need them all is debatable; do you really need to have players in the Maltese 6th tier or Fijian 3rd tier appearing when you are based in England, for example?
