Market Day: RPG Economy Software

Have you ever wanted to do stuff like vary local prices? Imitate supply and demand? Ensure there's more to look at while shopping?

If so, you probably encountered the same issue: it takes a lot of work. No more!

With Market Day, you can imitate a full economy with weighted rarity, settlement size, and price variation, all based on a random seed. This means that if you use a town name as your random seed, the results will be the same every time. If you change the town size, you'll get similar results with slight size alterations without completely throwing the table out. If you give your players this software, you can give them access to a market by simply telling them the name.

The whole program runs from a high-speed web-interface using an embedded html file right from your computer.

License

You have permissive license to use this software with your gaming group. Once you own it, share it freely with your players. This is how it is intended to be used. They can all see the same list of items based on the random seed, and you can let the software do its work to simulate the economy without input from you.

Functionality

The software works based on a .csv (spreadsheet) file. You can select any properly configured spreadsheet to build a market list from it. The included spreadsheet is suitable for any psuedo-medieval fantasy game, and the base values should translate into the typical d20-based games. While no magic items are included, they can be easily added to the file yourself by following the directions in the provided documentation. Want to switch genres? You can make any item list work, provided you build the .csv correctly. Again, see the provided documentation for complete directions.

Once you've got the item list pulled up, you can use the quantity column to buy and sell items at the listed rates. Select everything you want to purchase or trade or sell, then click the "Show Receipt" button. Your entire transaction is itemized and totaled for you! You have the option to download this receipt as a text file to share with your group or retain for personal records.

Just want to share a quick item list without the hassle of distributing this software to players? Export the file to a print-friendly pdf for sharing and printing! Your current variations will be preserved for everyone's use.

So if you want to enrich your game, increase the immersion of your players, save yourself time, and have more fun...
