Myst is the first installment in the Myst series, and one of the best computer games ever- in my opinion, it's only topped by Myst II and Myst III, its sequels. Beautiful scenery, puzzling (but slightly less puzzling than Myst II and III, so it would be better for a younger person), and altogether a wonderful game to play. I would also suggest a walkthrough for this as well, but it isn't as necessary as for the nest two games in the series.
