If you have to read things, roll things, or hide things, it's not an abstract.
(This fails to include backgammon and Parcheesi when maybe it should, and includes Zark City when somehow I feel it shouldn't, but it's not a bad starting point.)
Additionally: No dexterity (which is kind of a special case of "no chance").
i've always been curious about the gameplay, but have absolutely no interest in reading past words like "wizard", "mage", or "eldritch", and i won't look at anything where i have to see or imagine that somebody is wearing a cape, or even play with gamers who are willing to imagine they are wearing capes in other games.
If you're asking if there's a version of D&D that's pure math and no roleplay, the closest thing I can imagine would be Dragon Dice, or something with the mechanics of a very basic roguelike. The math in D&D itself such as in combat is affected by your character's stats and the encounters created by the DM, so the mechanics and the role playing are kind of tied together.
I am also past the age of wanting to believe in magic. And also past the age of having time for long plays. Most of my friends are busy doing serious adult stuff.
So outside of baroque dnd-like systems, my personal favourite right now is a subgenre called journalling solo RPG, which are often minimalist, but covering all kinds of themes and topics.
Now, the genre itself, all the storytelling involved, can easily be adapted to more serious, or even abstract, thinking.
In fact, it was, and there are plenty of alternative rpg universes. But, similar to how serious non-marvel movies are a niche, serious rpgs are also less popular.
