@Rei_Ayanami:

So, style is important, but if you make a AAA texture/model game with horrible scripting it´s even bad !

Perhaps , but like the last Wolfenstein , you will attract visually lot of people, and a lot will buy it , even if it is a basic FPS with stupid AI

Or you can make a Zombie FPS , stupid AI needed , and have great graphics and cool standard FPS gameplay : lot of people will buy it.
