My master of magic board game idea had a lot of concept in that direction because I wanted the game to make it infinitely expandable without breaking the balance of the game.
Some key elements was:
Non splitting of resources. Instead of distributing resources between various actions, all action had access to all the resources (for example, instead of spliting 8 resources between 3 actions, all 3 actions will use 8 resources.) So there is less accounting to do and it's more a comparative operation.
For the action system, I used a fixed 5 focus system where 3 focus are chosen each turn. A focus would execute a certain list of actions which was variable. So further expansion or modification could add, remove or change actions in a focus. This would allow an infinity of modifications.
But the number of focus is always 5 and players still choses 3. And all actions have access to a complete set of resources.
So there is no difference in game balance to run a focus that has 5 or 500 actions since the nb of actions has no impact on the effectiveness of each individual action.
Hope that makes sense.
^^This :D^^
Of course, I would also develop expansions... But I was trying to figure out how it would be possible to generate MORE scenarios. I remember a guy who had a $500.00 contest and collected ideas. Some people did not like that. So I figured the game should be OPEN when it comes to "expansions".
I know that's why I said it requires more thinking (aside from the logo and such). Not only rules, but also some designing guidelines.
The idea that some designer could buy the game and then design an expansion for the game. You absolutely need the game to design new expansions... I've tried to think of other ways - it's just not possible. Things like PNP (too much labour) or TGC game (just as costly as buying the game!)
So the easiest thing to do is MARKET the game to designers also.
