Game- Investigate

For this project I need to make a game that relates to a class I am currently taking.  I need to give an overview of what this game will be like and how it will be played.  I am doing biology and using cells.   got many different cites that explain the structure of an animal cell.  I will create a box, pieces and the art for this game using photoshop and ROME.  I also think that this other biology game where you create a character from DNA would be cool.  I think this would be more fun so I am rethinking my cell idea.   I think it will take about three weeks.  My goal audience is freshmen or middle schoolers learning about biology and giving them a fun way to learn about it.
these are the cites I found for the cell game;
