The thing is, I have limited time to play games, so I can be very selective what I spend that time on. This means I can limit myself to games that do everything right, not just one thing. That means story, but also production value. Good acting, good mo-cap, good graphic, a good sound track, etc.
Why would I spend the limited time I have for gaming on games that don't check all the boxes ? There may not be a lot of games that do, but there are enough for me to only play those kinds of games.
But honestly I don't play AAA titles because they are expensive (don't feel worth it for me, so similar argument as yours), and are designed for long immersive sessions and not 20 mins here and there. There are secondary factors like Linux compatibility and disliking the companies. For story and visuals I prefer films. Second hand I hear that mainstream titles are either designed stupid easy, or in a small niche with spiteful level of difficulty, but this is probably exaggerated sentiment.
I like films, but the problem with them is that they have to cram a story into 2 hours, maybe 3. With games being 20-40 hours, there is much more room for in-depth storytelling and world building. Also, being in control of the main character makes a story hit differently from passively experiencing it.
because they were first. Look at later games from the list http://www.wadjeteyegames.com/games/
Gemini Rue, Primordia, Technobabylon, Shardlight, Strangeland, but especially Unavowed!
Clifftop Games Whispers of a Machine and Kathy Rain are also good https://store.steampowered.com/developer/clifftopgames/#brow...
This in effect is why you're indirectly picking games with massive advertising budgets - they're far more likely to reach you than the average lower budget indie game.
It's fine that you like games with high production values, but don't just cast the lower production ones into this 'low-value' bucket and never look at them. AAA games might be diamonds, but you might just find other types of rare stones in the other buckets.
I have yet to see a story as good as the Blackwell series. Perhaps you have made up your mind that indie games do not have good story lines, so you are not looking for them. I don't know.
