Honestly.....I like big azz games where I can sink 300 hrs into a huge but fun world.
A lot of gamers have shorter attention spans and want more of a "movie-game" with a linear world, tight story and excellent gameplay versus story with more decision trees, more open-ended (ish) writing and perhaps good instead of excellent gameplay.
Linear game market will gain popularity because those games are easier AND cheaper to make with shorter production schedules and the potential for higher profit margins. Not the biggest fan of linear games unless it's something like Hitman where you can use multiple methods to solve a problem....but that might be the future.
