I met some people who play D&D 4E, so I gave them the stack of 4E books that have been sitting in my living room for a year and a half (and in various other places before that), largely untouched.
In true draconic long-view hoarding fsahion, I kept the core 3 books in the odd chance that I needed to run a 4E game- all the other books were really superfluous.
