sex sells, you don't see fat ugly people in beer comercials, do ya?

if you do a google for "nude game skins" the first sight that comes up has most all of the nude or sex patches for most every popular game there is, Quake 1,2&3, Duke Nukem, Tombraider, the Sims etc. there is even a patch for Brittney Spears Dance Beat (which looks very similar to 3d Bikini) and low and behold there is an affiliate link for Jak's Strip Kittens (the nude version)

In the thread on USA Bass there is talk about the game being on Warez sites and that meaning you made the big time
A more realistic approach might be your game has made the big time when someone makes a nude patch????? and in Jak's case he has both versions and like has been said earlier is LOL all the way to the bank!
