When I was younger, I was a big fan of the board game Risk. I would play it with my friends and as the years wore on, I added rules and adaptations to its original rules. Recently for one of my college classes, I was asked to create a board game from scratch. I decided to make a modification of the game Diplomacy using some of my old Risk rules and the original Diplomacy rules. Using Photoshop, I created a modified map of Europe vaguely following the province lines of major districts in the EU. With this, I created the modified rules with the map in mind.
Here is a Google Drive link to the rules. Feel free to use it as you wish.
