Chances are that we’re not in a simulation, but you’re right that for our universe to be simulated, the host universe would need fundamentally different physics.
Even then, I feel like you’re underestimating the scale of the universe. Dwarf Fortress is laughably simple compared to a real universe. It’s a toy. You’d need something more than a couple extra dimensions for our universe to be at all comparable to that.

To be completely honest, dwarf fortress is way more complex then tic-tac-toe.
