1) Ability to define a time-limit for the game to progress from lowest to highest level.
2) Along with above a "Timeout" that declares a winner based upon $$ and a bonus action <??> for winning.
3) Ability to "Pass" on an action and receive an alternate -- for example if it is an unexpected turn-off, exceeds comfort zone / available time / etc.
editing to add some thoughts...
4) Place: Night School -- actions are 'homework assignments' to be performed between games.
5) Ability to save clothing configurations.
6) As posted in another thread -- a Wizard mode for the action editor.
General observation, no ideas in this realm but I wondered what others thought:
For my wife and I the "game board" almost doesn't exist. I'd say the only time I look at it is when I'm trying to decide what sort of builiding to make. This is probably a good thing in terms of porting to a handheld device as I think the board could simply be eliminated. However with the PC game, it would be nice to use the gameboard in a strategic way. Maybe different paths you can select etc.
