Making a single great game is one thing, but spinning a hit title into an enduring franchise which continues to surprise and impress gamers for years or even decades? That's no easy feat.
Practically every long-running video game series sooner or later hits creative stagnation, often resulting in them outright floundering critically or commercially - if not both.
For many franchises, this will force them into a sabbatical of-sorts while their publisher tries to figure out what to do with them. The next step is absolutely crucial in determining the future of the IP.
Some publishers will simply decide to cynically cash-in on current gaming trends whether it suits the game or not, while others will spring for wacky, desperate new peripherals - let us never, ever forget Tony Hawk: Ride's plastic skateboard controller.
But there are smart ways for publishers to rejuvenate their ailing franchises, typically through a combination of sticking to what made people love it in the first place, and acknowledging how their respective genres have moved on in the years since they began to fail.
These steps aren't ever a guarantee for success, of course - or that the sales will match the reviews - but are certainly the smart ways to go about shocking a video game series back to life...
