Just to see if I could, I made an SotM Randomizer in Google sheets. It compares the random game to see how difficult the game is based on Gray's stats. Or, you can first select how difficult of a game you want, then it will randomize it for you. Not sure if anyone would use this, but wanted to post it anyways. To select custom options, go to "File->Make a copy". If someone finds a bug, please let me know.
EDIT: Fixed a bug.
EDIT2: Fixed some more bugs. Also, now anyone can edit it and play around with it.
EDIT3: Updated Gray's numbers to the latest version. This gave numbers to a bunch of characters that didn't have it before.
