And pixel-hunt obsessively. The second game is far worse for hiding things from you and requiring nonsense actions to solve some of the puzzles (at least there's a hint system in the first one for some of the weirder things you have to do), but in the first game, they love hiding items you need in plain sight.
Also, if you can, play the CD version with voices. I grew up with the low-quality music from the floppy version, and most of the voices sound little like what I imagined, but Chris Barrie is Simon. That alone makes the voice cast great.
