Meaningful or Impactful Content, I like to finishing a game feeling I experienced something meaningful or impactful instead of feeling time wasted playing toys.
When I was younger I prefer fun game mechanic over the content itself, but now its the reverse, for me video game is a tool to experience what in real life can't
With time becoming more precious, I prefer short but condensed experiences than long play time but loose experiences, many people ask the question "how much play time do I got out of X amount of money payed", but I ask the question "how many meaningful experience I got out of X amount of time spent". I like finishing a game by get the maximum amount of enjoyment in a limited time, and move onto next one, there are just so many great works out there while not enough time to experience them all.
You see some game require grind and meaningless side quests or exploration to inflate its play time, I'm not a fan of these types of game anymore. I'm not against exploration or side quest, its just with the amount of time spend on them I would rather play another game's main quest.
My preference on this media might be controversial for many, but for me no matter how fun the main play loop is, its just the same thing over and over.
People often hold "the ways of interaction" in video game to high regard, after all that's what separate this media from others, I don't disagree, but I would like to add "what content are you interacting with is also important".
I never understood when did the word "linear" automatically translate to "bad game design", for me linear games have a special charm where the designer could hand craft condensed and impactful content manually that provide the player the best experience to time ratio, so you don't have to waste time wondering around hunting, cooking, fetching randomly generated content while doing the same play loop over and over. If I want exploration, I'll rather take metroidvania level design, at least everything is intentionally crafted.
In terms of actual content, A 30 hour play time open world exploration ≠ 30 hour play time handcrafted linear experience
I still recall the 8 - 10 hour I spent on Silent Hill 2 is an experience worth life time remembering and certainly worth the full price I paid back then, that's the type of game I prefer, yes its a linear game.
