You're not doing much "making your game". You do not change properties more than add a photo. The board only allows for some small photos and the pieces are again just a small photo with the addition of a monopoly themed stand. If you're looking to alter the game play, you can not.
It's really cool comes with an app you can download pics, and put your own pics on pieces - comes with dog, cat, racecar, and battle ship! You can also put pics on community chest and chance cards!
My dad always puts in a joke gift of himself in our yankee swap, this year the joke will be on him... literally!!!
