I really liked "Nemmesis Oriflamme", altough itīs not a RPG, but the first scenario is one of the best iīve played.
And, of course, "Knight of the rose", one of the first RPG scn out there. Try with "The emissary", i think it was the first using the click-and-talk trick."Legend" and everything that Gordon Farrell has done are very good too.
"The guardian" and "A man alone" are good RPG too.(donīt remember the name of the designers)
And try Derfel Cadarnīs ones : " Cortez unification of Yucatan" and " The Chronicles of the Warlords".
And why not, try mine : "Percevalīs Quest" and "Penitence City".
If i can remember well, all this scn or campaigns are in the best of the blacksmith. (wait, maybe nemmesis oriflame doesnīt,but i really suggest you to try it.).
