I will throw out the website I put together a few years ago for my custom pin:

pathfinderpinball.com

The site is extremely outdated, especially the build log. The theme is based around the 8th Air Force in the ETO. It isn't done and the cabinet mocks me when I go to my workshop, but I am still very committed to finishing it some day. Since I started it (and life got in the way) many customs have come out and those builders have done remarkable things. I am encouraged by their success.

I find it interesting as I never thought the theme would be offensive to anyone. I have an Uncle who was KIA over England in 1944. I have done extensive research into him, the crash, and have information from both sides of the conflict along with family artifacts. My theme was always going to be generic and was never going to focus on any past of the family story. That is something that should be shared with people on a more personal level. And if someone plays the game and asked for my inspiration I would absolutely share it, but not on the table itself. It is going to be more an homage to the job we asked our soldiers to do and those that did it. I maintain there is a way to base a game on this period of history. But then again it isn't possible to please everyone so those folks don't need to play it.
