I feel you there. Just a sketch for me of the layout is enough, doesn't have to be super detailed, as I can picture and remember the rest. Otherwise, I like playing TotM.
I find it more practical the less a game cares about distance, cover and involves area effects. I was able to run Scion 1e TotM, but there are few other games I'd actually bother to run that I'd find practical that way.
