Maybe, but there's no reason we can't leverage modern technology to make new games that aren't trying to look realistic. Realism is just a style, and it's not the best style. It's just the "premium" style that sells new games. It also ages like crap because technology will always get better at that. A stylized design ages gracefully and can be a lot more performant and potentially easier to create too, though it requires more creativity and more work with the engine than just using it as it comes.
I made a point a few years ago to play through every single unplayed game in my steam library. I'd picked up over a hundred games from random sales and humble bundles, And thought it was a disservice to myself to have unplayed games while buying new ones. This was one of them. I think this game had one of my favorite stories of any RPG I've ever played; it was number one until Baldur's gate came out. I later learned it was a spiritual successor to planescape torment.
If you liked this one, another gem that I played during that time was Tyranny. I'm currently working my way through pillars of eternity; I'm really liking it as well so far.
