This article on Final Fantasy X-2 details the apparently very large number of costumes that the heroines of that game can wear, depending on how the player develops their stats. It’s a fairly risk-free way to add value to a game.
Wired argues, a bit unconvincingly in my opinion, that FFX2 is part of an effort by game developers to address the female gamer.
On the other hand, Dead or Alive eXtreme Beach Volleyball also features female protagonists and many different outfits that the player can select.
“Anyone who dismissed this title as a lame excuse for slobbering perverts to parade hot digital chicks around in various states of virtual undress… well, you’re only half right.”
Predictably, Acclaim announced a highly similar title. Will it feature strippers?
