Think is mate, end of the dayu they are just a game though, yeah they have networks of people compiling data on players etc and doing estimates on player potentials etc, but i can guarantee for every player they get right who goes on to be great they will get 10 wrong, but people remember how this 17yo croatian lad they signed became world class when he does and forget about the dozens of 'wonderkids' in the game that turn out to be absolutely rubbish
As i said though haven't picked one of them up for about 7-8 years now but can't see that having changed really
The game was designed to let you win everything you can do and dominate eventually with any team in the world and a ssuch is as un lifelike as you can imagine.
Unless you think that Estaban Diaz the manager of Sabaddell (me) was that good that he took a team from the spanish 3rd division with a part time team to win the CL, Spanish league and become the manager of Spain and his club side at the same time winning the world cup
As un lifelike as you can ever get, same with FIFA, games are meant for the lowest ability level to win
