I've a healthy amount of old mods from all editions I'd like to see used in 5e. When adapting older adventures, do you recalculate treasure?
My game is only 3rd/4th level, but thus far I normally halve to quarter cash from 1st/2nd edition adventures. Potions I leave as is, some scrolls I leave as is. I drop at 2 "plusses" from magic items (though not to -1). So a +1 sword just becomes a regular sword, a +2 sword becomes a non-magical quality sword, etc. I've been big on giving out consumables, making those much more common than 5E assumes, but since they are going on a slower advancement track (and don't always have a healer other than the paladin), they also use more each level.
As far as older adventures, I'll always stump for Return to White Plume Mountain as a fantastic adventure, better than the original.
