No cheating! These are from a time when games were hard, and had no "difficulty" setting. Keep a pencil and paper on-hand, and be prepared to make large maps and tons of notes.
I've attached an emulator, and the following games (to be played in this order):
- Zork I: The Great Underground Empire (1980)
- Zork II: The Wizard of Frobozz (1981)
- Zork III: The Dungeon Master (1982)
- Beyond Zork: The Coconut of Quendor (1987)
- Zork Zero: The Revenge of Megaboz (1988)
- Enchanter (1983)
- Sorcerer (1984)
- Spellbreaker (1985)
