In response to a query at EN Word I spent part of last night hastily assembling this page about using the map from the old AH game Outdoor Survival with OD&D. We may have to spend a session or two of my next D&D campaign exploring a map like this. Maybe not this exact map, but at least something similar.
I'm also thinking about adapting Dave Hargrave's ultraviolent critical chart from Arduin to my new campaign. This chart would not replace the current system but would supplement it. When natural 20's are rolled both on the to-hit roll and crit confirm then you would get to use the Arduin chart in addition to the normal crit rules. Similarly, a natural 1 followed by a second natural 1 could send you to Hargrave's fumble chart.
