There is an interesting parallel in nerd culture generally.
Once upon a time, to know, experience and feel the universe of comics and superheroes you had to invest deeply of yourself, mentally and emotionally, to enter those worlds and bring them to life. Special effects and pre-charistmatic actors now do all the work, and the door is open to the casual passer-by to consume.
Video games are in this stream as well. You had to give of yourself generously, to suspend disbelief entirely, and invest in imagined, or external backstory, art and detail to experience worlds rendered in limited dimensions and blocky pixels. Video games are now mainstream, as the game meets you far more than halfway in creating an immersive experience.
These aren't bad developments, and they aren't destructive to genres, but they do render the imaginary labor into pixels and pages as part of a nostalgiac/minimalist art experience, rather than a rite of passage into an exclusive world.
