Dave Lebling

Dave Lebling was one of the original Zork implementors at MIT and a co-founder of Infocom. While Marc Blank focused on the Z-Machine architecture, Lebling pushed the creative boundaries of what text adventures could do - from the procedural mystery of Suspect to the complex NPC interactions of Spellbreaker. His games were known for clever puzzles and technical ambition.
