ok I just want to know, what exactly should be inside a GDD?
because from the T2G book it tells us the weapon, attacks, characters, enemies, items, inventory, etc should be documented in the GDD.
However seeing other people's and companies GDD, they have the high concept as well as the pitch documented with the T2G:/
is this right? I mean why should the Pitch and high concept be merged alongside with the GDD?
Game Design Document should just contain all aspect of the game design, should it really contain story ark? pitch document? high concept? summary? art works? level designs?
I do believe GDD can contain Technical design document as well.
