Aside from all of this PS3 console ID crap, I don't think it'll be too bad. I taught myself the Xbox method without asking anyone about it. It's unbelievable the amount of people who don't seem to know what google is! Haha.
But anyway, yes, a lot of preset faces are hidden. From the likes of Patrick Vieira, to Hitzlsperger, to Sol Campbell.. you'd be surprised the amount of players in the Classic teams they've left on the disc etc. - and with w!LD@'s PC editor, there is a list of who's in built into it. It may take a little time getting used to everything, but the result is definitely worth it.
Do you remember the Clint Hill face you created with that Australian player's hair (I forget who) which you had to change for PES2012, Meat? My version still has the original hair
THE POSSIBILITIES ARE ENDLESS! Haha.
But yeah, you could do the export team thing, but personally I prefer having the quality control myself. Depends on your own preferences, I suppose. But you could get someone to make a team with the likes of Hitz, McFadden, Boruc, Beckham, Vieira, Coupet, Wiltord, Henry (just incase for you gooners
) Van der Sar's presets etc. yes.
