The original was called "Bad Dudes" and its intro went thusly: "The President has been kidnapped by ninjas. Are you a bad enough dude to rescue the President?" As you can see, this concept is pure gold, but underexplored. But now, thanks to this random concept generator, you can get inspired by the millions - nay, BILLIONS - of possibilities - nay, possiBILLIOties - that this generator can spew forth at the click of a button. Then it's up to you to make the game so that it can be played! This generator doesn't create the games as well, sorry! :)
Post your suggestions of more things to add to the lists for "President", "Bad", "Dudes", and "Ninjas" and I'll update it sometime.
