Play it without the guides. It is way more fun. Part of the fun of that game is discovering new stuff and finding all the hidden things. A guide would defeat the entire purpose of playing it. It is not that hard of a game anyway.
I found them quite fun back and the day and when I played the original a year or so back I still had a lot of fun, despite the game feeling dated.
Nuts & Bolts. I should play that again. That game is a blast.
