There are very few bits of IF that have stayed with me and will do forever. So Far is one of them, which in a way is a terrible shame, because it's almost impossible to share with anyone else. The game is famously difficult and cruel (it's the only game I can think of that actively encourages players to do self-destructive things) and to say I got through it without hints would be a lie, lie, lie. But it was a beautiful thing, finely wrought, casting shadows across itself like a spinning sundial. It made me feel horribly jealous not to have written it and deeply privileged to have played it. Sigh -- those were the days...
