Your poll would probably be more useful if you included a negative response, such as "Haven't Played" just so that you could gauge responses. Just a thought.
Unfortunately, I haven't had the pleasure of either DMing or playing in a Scarred Lands campaign. Once my current FR game runs down I will switch to SL since I love the setting. However, this could take a while as all of my campaigns are planned out to be long running ones.
I've been GMing a Scarred lands game for a little over 12 mnths. Although its on a bit of a hiatus at the moment so I can actually play something for a change. The first time since....
I am still involved in a revived Scarred Lands PBeM, set in Mithril. Damn Pisceans.
