Worlds Apart

Suzanne Britton's "Worlds Apart" was the first interactive fiction I ever played, and it remains, to date, my favorite work as far as quality of writing goes. Its gameplay is relatively free of annoyances such as hunger puzzles and sudden death syndrome, which is notable considering it dates from 1999. I had some guess-the-word problems playing, though some of them were intentional puzzles.

I recommend this game to any player of at least moderate experience playing I-F.
