If you're sick of this industry being dominated by sequels, then stop buying them.
David Cage shared his disdain for video game sequels during an interview with OPM UK. His belief is that they stunt innovation in the industry, and have thus caused stagnation. He said:
If you’re interested in innovation and believe that games could be more than shooters, then you realise that sequels kill creativity and innovation.
The Quantic Dream development team is currently working on Beyond: Two Souls, the spiritual successor to Heavy Rain. Although it incorporates similar qualities and concepts, Cage is confident that it will differentiate itself from his previous work.
We don’t give people what they expect. We want to give them something they want without knowing they want it.
If Heavy Rain is any indication of the values of Beyond: Two Souls, then the industry is in for yet another enlightenment. What will be fascinating is how, and if, it's able to be truly original. Development studios have been exhausted lately, with new experiences (i.e. Journey, The Walking Dead: Season One) being few and far between, especially when compared to previous generations.
