Game-based training system lifecycle support

We see systems like DARWARS AMBUSH! pressing to become a program of record. But, with a game-based system that is burned onto a CD and largely self-explanatory, what type of lifecycle support will really be necessary for it? Perhaps these types of games can survive in the military with a much smaller organizational support footprint. Perhaps one Project Director could be responsible for 30 game-based systems deployed through the Army. What type of support does a game really need? Is it significantly different than our more traditional systems/devices?
