The modern gaming mindset is much different. Lots of people in the gaming communities of today can't comprehend deep stories like Tactics. I'm not calling people stupid, but they don't expect that stuff in games anymore.
And Tactics and Xenogears are both very deep and have compelling stories, maybe the best stories of all time, but in ways are socially unacceptable due to "going against God" and some religious tension.
But come on, there's enough of people like me and lots of others who love deep stories that make a man/woman think. And your facial expressions stay dull, but it's because inside your mind is blown by so many things.
