Pretty much, you can have a setting when you create a game to have these in your game, separate from one another:

Instant build/research/production
No research day limits
Double Production
Free High Command Mode (lets players see what high command is like, so that they may want to purchase it later)
super fast round (all production / research / movement / build speeds are 100 times faster) (sort of like atwar)

These could rounds could be tested in one of the "event" games.
