I can respect that.OD&D.
I like the fact that it gives me a simple set of basic mechanics and gets the hell out of the way. "Here's basic character generation, a simple combat system, some spells and some monsters and some treasure. Add imagination and go apeshit." Remember, the spell research rules came BEFORE the spell list.
AD&D 1E - I loved all the world building stuff in the DMG. (The Random Harlot Table makes perfect sense to anyone who ever read Fafhrd and the Mouser.)
Hated everything since.
