Well, seeing as I am the artist for this whole thing - so say the girls - I can only answer so much here. Now, time to start with what questions I can answer...
The game is definitely meant for teens and young adults. Perhaps you could fit a few others into this group, but this is just a general idea.
Definitely, I'm quite sure of this, that the game will teach... Wait for it... MONEY MANAGEMENT SKILLS! ^_^
The game world is, of course, going to be a mall. I'm bound to throw in a GameStop, a Hot Topic, and, more likely than not, some sort of random salon. It will likely be based on the Meadowbrooke (not sure about my spelling) Mall.
It will probably teach people how to use the maps in a mall to find out your current location, your destination(s), and possibly a bit more. Whatever the girs want to code into it. I'm not to set on anything in particular.
And, of course, there will be lots of shopping involved. You might want to mind your money - I'm going to find some actual item prices. XD
Hot Topic isn't a cheap store, you know.
Oh, and can't forget this game is going to be better than a quiz for the reason I know and love - experience is better than a piece of paper. Oh, and this will be more entertaining than some boring quiz... although I kinda like quizzes... o w o
