Yes, but we're all basically familiar with elliptic geometry, and as a result it's not terribly interesting or surprising.

Hyperbolic geometry, on the other hand, is alien to most people, (especially fractal like the projections into 2d and 3d), so when people wave their hands and say 'non-Eyclidean geometry!', that's what they usually actually mean.

Try actually watching some of the hyper-rogue gameplay: https://www.youtube.com/watch?v=lX5eCfRSCKY

I assure you, it's more interesting as a geometric visualisation than planetary annihilation is.

Yeah it’s nice but at his core non-euclidean geometry is just about the parallels axiom. The dimensional aspect is what makes this game interesting, not the euclidean aspect.
