Possible Games We Can Play
The problem I ran into when researching potential games was the tendency for most games to either be more oriented toward the simple game-theory aspects (http://en.wikipedia.org/wiki/List_of_games_in_game_theory) or focused on virtual representations of real markets (http://www.google.com/search?q=market+simulator).
The couple I did find seem to fit in a third category, in that they are full fledged computer games that have many aspects and variables without depending on real markets–pretty much what we’re looking for. (http://en.wikipedia.org/wiki/Capitalism_II, http://en.wikipedia.org/wiki/The_Corporate_Machine, http://en.wikipedia.org/wiki/Beat_The_Market, http://www.topshareware.com/Wall-Street-Raider-download-1499.htm, http://www.amazon.com/Marketing-Game-student-CD-ROM/dp/0072513802/ref=cm_cr_pr_product_top) If you read the descriptions, you will see that each of these has distinguishing features, so we do have a degree of choice depending on what kind of program we want to make.
I could not find any APIs for any of these games, but I was unsure about what exactly to search for.
