I can't see why it is necessary to have orientable surfaces (i.e. having
two separate sides to it, which Mobius strip doesn't) only.  Just make it
"trasparent".  Besides the game is really not on a surface but on a
lattice.

But your main point:

is completely right, I think.

or indeed a map where you can only move west and never east...
