For the epic game I am creating, I plan for it to be a large scale game. However I have been contemplating creating a number of mini games that can be played with the same components included in the box. So a player could have a long solo game or a long game with friends, or can choose from a number of optional smaller games for multiplayer, by referring to a booklet that contains all the rules. I figured in this way, I may be putting a lot of energy into creating this huge game, but it would come out being a lot in one box. It's like, you buy this game, and get so much more for the investment. Is this something that other games have done?
Then, there are "expansions", and that is a whole other thing.
