Dark Sun, original edition.
The revised DS box is really cool for the expanded area it covers, but the original has a feel and atmosphere that is unmatched for me, a lightly sketched world just dripping with adventure. We're over thirty sessions into streaming a run through the classic DS adventures on Twitch at the moment and it has been great to see the world come alive for players who are familiar with the setting and those who were brand new to Athas when we started. Such a great piece of design work
