The Storm Crows - High level storypath 1st ed romp through G1-3, D1-2, and a couple detours. These guys are numbskulls but hilarious to read about.
Tales of Wrye - High level storypath 3.5 Excellent example of character growth. War and planes as high level content. It's also a great story.
Melan's Fomalhaut - Low level sandbox OD&D? Sword, Sorcery and Rayguns! (no monkeys yet, sadly)
What I've not encountered is higher level (9-10 plus) sandbox or old-school/retro games. Also, I've read here and there at old-school haunts that low level play is preferred by many of that ilk. Several abhor the latter letters of BECMI. Then I found out that my current campaign inspiration The Western Marches only went to lvl 6-7.
I'm curious, does sand box not lend it self to high level? Do OD&D, clones, simulacra and the style of play pushed by the old school mainstream break down at high levels? Do campaigns / players just start over after a certain point? Can anyone point out some good campaign journals that demonstrate the opposite (high level sandbox or high level AD&D?
And apropos to nothing I find my self in total agreement with the Pundit.
