I won't claim to be in a majority of the market share, but there are still a decent chunk of people like myself who dislike open worlds and game altering decisions. Plus the fact that there are already a whole bunch of game like that. I don't see why all RPGs have to cater to that direction.

Also dialogue/plot choices =/= decisions affecting the gameplay. Something like assigning skills/jobs is a difference that affects the game play. The former are decisions that affect the game progression.
