The short version
@slamsoze is you choose a team and start with the default players and you play mini leagues winning them to unlock others. but the best bit was that when you win you get to choose a player at random from the other team to sign. and you do this after every match gaining more picks as you go along. Thats what its like in pes 2008 in pes 2009 etc its the same buy you can unlock like training ground expansions to get better competitions with better players.
here is a video of what happens when you win a match on pes 2008 version(btw there was no master league on that version on this game mode)
There is also a playthrough on pes 2012 wii (only a few parts theres only 3 in this playlist but i think he did like 6 parts)
Absolutely loved that mode. The cards system was upper fun.
Two cards association could unlock one "special" card, an some special cards togheter unlocked "unique" cards. You got some to get for example "80" on speed to unlock a card etc.
It was even better on the 2009 version.
It was upper cool. I gotted 2008 and 2009 version (similar to PES 6 but better of course, nothing related to PES 2009 "next-gen" for example)
Also i loved the controls, you could launch for example 7 players in attack if you click on them and gives him a direction.
In terms of "full team control", it was by far the most tactical football game ever. Well, for shooting you just got to shake the Wii controller and it was managed by stats only, but it didn't matter at all regarding the system and the freedom you could get with Wii system controls.
Parking the bus manually or left a winger in attack, separated from the whole team, forming a block in the middle etc.
It was PES with PS2 engine (who was already good), but a totally different game in fact. You can't compare, it was more like a mix between a game like some PC tactical RPG with multiple people to move in the same time, and a classic football game.
Dribbling was cool too, but as you saw on vids you couldn't dribble with 360 degree directions, as it was with the nunchuck pad if i remember... But i don't remember if you could select your player and assign him an arrow to make him run or advance to any direction you wanted (I think so if i remember well, so 360 degree but not dynamic as it is with an analog pad)
