Patents and video games huh? We can’t ignore what John Carmack had to say about this:
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.
–John Carmack
Name a game you have enjoyed that isn’t a ripoff.
