When will people realize that there's almost nothing that's original anymore? Everything is not "copied" from something, Assassin's Creed was apparently "ripping off" a book because the plots were similar. But the thing is, something is similar to EVERYTHING.
It's not ripping off anything. Maybe it was inspired by it, I've written things that I've been inspired by. Now if you see someone using the name Slurm where the mission/game is essentially the plot of the entire episode, THAT is a rip off.
