I saw Slender and "Dream of the Blood Moon". I like to create things with Sculptris and animate them with Kinect. Which game - or Gamekit - makes it easy for me to see my own creations in a ready-made world appear? I would like to start with replacing the characters first for several actions then maybe change the virtual world.
Finally I would like to offer the game for free as the others do.
Is it a good idea to use c#'s XNA for that?
EDIT: Unity is using c# which works in my favour. I created my first game, download here if you want. Feel free to test for troians, virii etc. Link: http://d01.megashares.com/dl/SLa3wuk/mlm.exe
