Basically as in-depth as Madden or Nba 2k11(I would say fifa but never played it)

• Simple head morphing(length,width,protrusion) for skull,nose,eyes, etc..
• Have skill attributes restricted  by physical things such as height and weight
• I like the idea by the OP for the arms and leg,but for the whole body i.e. Madden body sliders
• Tattoos Tattoo...oh wait i forgot tattoos
• of course accessories:gloves headband(thick and thin), sock length,scrum hats,armbands,shoulder pads,compression shorts,nike pro combat gear!
• Add soccer cleats/boot..whatever im american..but like the fifa creation center thing
• all the Fifa hairstyles but add more beard/moustache combos (some really rugged full beard stuff)

• Last thing there should be a way to either submit your name somewhere either in the game or some other place so the Commentator can SAY YOUR REAL NAME

Cause i know my last name "COMPTON" would never be said
