There is has been a lot of talk in gaming circles about Universal Horizons and their attempt to patent an RPG mechanic.
You can find most of the details here:
And here is their patent application:
Now as is it read it is vague on what "Game 1" and "Game2" could be and some people are claiming that this patent could be used to convert from different games instead of the games within Universal Horizons' own catalog.
Also there is the fear of what happens if the patent is bought by someone else. You see it all the time in the tech market.
I don't have much more to add to this, outside of my realm of expertise, but I do know I have been converting from games to other games for years and have been posting about them for years too.
So then in my efforts to give back, here is my "super secret" method of converting and the tool I used to do it. My "All Conversions" excel sheet. I figured out the math and works for me. Let me know if you see ways to improve it.
