The game is more fun when you use extra stuff for FM12 like graphics pack and real name for competitions. In this post I will show you what kinda of extra perks I use and where did I get them from.
Real Player and Staff Faces
I just hate playing the game and not have the pictures of the players.

I use the the Sortitousi Cut-Out Faces Megapack Version 4.0 which can be found here: http://sortitoutsi.net/forum/topic/39782-megapack-home-thread-latest-update-40/
Club Logos
The same as with players, I like seeing the real club logos.

I still use, Like in FM11 the D’11 Logos, which I got from here: http://www.footballmanagerfanboys.net/discussion/topic/932-d11-logos/
Unfortunately, there is no megapack, all the leagues have to be downloaded individually.
Kits

The kits I like the most are FbKits, which can be found here: http://www.footballmanagerfanboys.net/discussion/topic/5425-fbkits-download-area-season-1112/
Real Names for Clubs, Competitions and Awards
I don’t like playing the game with made up names for club or competitions. To get the real names for clubs and competitions there is a fix that can be found here: http://sortitoutsi.net/forum/topic/53651-fm12-susie-real-names-for-clubs-competitions-and-awards-fix-v1-for-fm12-now-out/
Skin
There aren’t many skins for FM12 at the moment and none of them is really good anyway. I used 3 skins in FM11, two of the where Neue2 and FM Crowd skin. There was a 3rd skin I used for the most amount of time which is now available for FM12.
It is actually the base skin of Football manager, but it allows some further customizations. The skin(s) can be found here: https://sites.google.com/site/michaeltmurrayuk/Skins/base-skins-for-football-manager-2012
On the link can be found more details on what changes are possible.
