Whne its creating the "New Game" Special it isnt creating any map location, etc.. (look at new game) and what would you like this specail to be a new game + or just a harder version as either way you need to set the variables Game_Party etc to values if you want it to create a new game with specail conditions by modifying values such as:

$Game_Party = Game_Party_Special.New with "Game_Party_Special" being another class.

Hope that makes sense
