I started looking at lots of different rule sets for D&D style games. I played D&D quite a bit when I was a kid so I'm pretty familiar with the basics rules. I wanted to get a feel for what different kinds of rules systems existed for table top version of these games. I picked a few of my favorites and started working on the basic code structure. The idea is to have the core rules run as their own simulation to drive the visual aspects of the game. This is pretty typical for game development. Once I'm done with this aspect of the game I should be able to run a complete game with text only output which will make testing pretty easy as well. 

All of the table data is formatted as CSV files so I can import all of the data from a spreadsheet. For now I hard coded the data tables as CSV blocks of text. When I moved the data to a spreadsheet it will be straight forward to export it as CSV or even call the google sheets API or something like that.
