A one-way would work with a cycle, or similar directed graphs (e.g. two nested cycles, where there are no CCW edges). Or like the one-way-street Wumpus map -- a lattice where north and east are the only options, except that the north and east edges wrap-around to the south and west edges, respectively. Leave, and you have to take the long way home...

Spymaster races might be excessively powerful in such a system, 'tho. It'd probably have to be disabled.
