Maybe, but there is something quite appealing about the world described by MERP and the I.C.E. Middle-earrth supplements that could be a better place to adventure, depending on what you want out of a game.
That makes sense. I'm going to reread OD&D (when the OD&D booklets came out in PDF I printed them all and stapled them into booklets), then write an adventure and after we've got used to OD&D I'll add Arduin.
I picked up the first three volumes of the original Arduin Grimoire recently because of the over-the-top energy they exude. How do you approach playing it now? Take the fighter and magic user from OD&D and use the other classes from the Grimoires? Throw whatever classes and stuff that appeals...
