I remember, way back, at least one person asked me why I didn't use fog of death instead of lava.. to sort of 'update' the map a bit more to a Q3 aesthetic or whatever. My reasoning was that, as rare as it is to likely happen, the lava IS escapable at times. Whereas the fog is not.

This is the second time I've heard of it.. but even just one makes me glad I didn't use the FoD.
