I was debating whether to get into this series. It's just so dated but I can see why others enjoy it. It does have a bit of an atmosphere.
Elden ring's mechanics are a lo of things, but not dated.
You are missing out on a great game.
I once was a bit like you. Seven years ago I bought a Humble Bundle that had Dark Souls 3. And I had never played any of these games before.
I started the game, killed a few enemies, then reached Gundir, the first boss. And I got my ass kicked a few times, I quit and uninstalled the game.
Many years later, Elden Ring comes out, and everyone is raving about it. So I took the plunge, ought the game. Got my ass kicked, but this time I insisted and got gud.
I finished my first playthrough of Elden Ring. Did another. And eventually I decided to give another try with Dark Souls 3, and it was awesome.
I wish I could go back in time and tell my younger self to "git gud". For years I was missing out on great games.
