I think one of the beauties of airsoft is you can play the role/character that you want be have a 1:1 outfit, gun and accessories (well almost considering we are playing with airsoft guns).
Good example is when "I am Legend" by Will Smith came out my teammate wanted the look of he's m4. After a few online buying....BOOM! exact replica. You want a PMC, russian ops, navy seal look....no problem! You can take a pic of a full geared airsofter and the real character and you can't tell the difference (with some exceptions of our heavy weight comardes.
The role playing + imagination + the 1:1 replica guns just gives the edge for me when playing airsoft.
