Acheton

Acheton (1987, DOS) is one of those text adventures where the game cheerfully tries to kill you every five minutes — and does so with words. You're tossed into a sprawling, brain-melting maze of puzzles so obscure they might as well be written in Klingon. There's no map, no mercy, and definitely no hand-holding. But for the brave (or masochistic), Acheton is a brilliant relic of interactive fiction — a reminder that once upon a time, people gamed with nothing but a keyboard, imagination, and buckets of frustration.
