how to build this genre of game with CI

[eluser]Michael Nielsen[/eluser]
I'm a massive fan of Virtonomics.com. It's developed in Russia i think and has a lot of flaws + they're now charging so I'm thinking of creating my own.

It's a business simulator and I can probably figure most of it out however I'm not sure how to create the update process; where the entire days actions are processed, e.g goods sold, buildings completed and stocks sold from factories.

The think i'm most unsure of is the algorithm which how many customers visit a store and the amount of goods sold, also the determining of prices by demand and quality ect.

any information is welcome. probably best if u create a account so you can get a better understanding of what I'm trying to achieve.

Thanks.
