I was spending a recent evening watching The Fugitive.
If you don't know the movie is about a doctor who is framed for murder and attempts to find the real killer. One of the major characters is a US Marshall played by Tommy Lee Jones in his best role ever. Five years later Jones' character would be given its own spin-off movie, US Marshals.
Television has had plenty of spin-off shows, for movies, it's a bit more uncommon, but what about video games?
Which games have had major, or maybe more successful, spin-offs?
