DON'T. PANIC.
Look, let's face it - this game is objectively ass. It was literally a scam, promising features that either never existed or were added as only surface level fluff via a quick patch. They lied to reviewers who played Beta versions of the game, describing stuff that they then based their reviews on (which, to be fair, the reviewers were really stupid to do, but it was maybe understandable because Sierra was a big company back then and why would they lie?) What mechanics it does have are pretty shallow and boring. One playthrough will be largely identical to the last, and you'll get mostly the exact same events and stuff.
And yet...there's something about it isn't there. The game looks the part. There's some sick obsession with the idea that, ya know, maybe I just haven't figured out how to play this correctly yet...and I think that it's a pretty notable title in history that ought to be preserved in some form.
