I'm running a home campaign set in Living Geoff (part of Living Greyhawk). I played in the original campaign for several years. I thought the adventures were fantastic.
Yes, the modules are constrained somewhat due to the "Living" aspects ... i.e. each module can't assume that players played any of the previous stories in the arc, can't even assume that the party is the same party or same dm that you had last time. That said, the stories are good.
Please feel free to contact me offline for more comments.
