Hero's Quest I: So You Want to be a Hero? (Sierra On-Line, 1990)A adventure/role-playing hybrid, Hero's Quest I was a welcome departure from Sierra's typical adventure games. Even though the game was essentially the same whether you chose to play with a fighter, a magic user, or a thief, there were a few differences in the puzzles encountered, and the way they could be solved. Genuine humor and lots of things to do, combined with an interesting (though not very involved) plot in several related and unrelated stages, make this a definite must for anyone that enjoys the role-playing or adventure genres.
(Note: This game was later renamed Quest for Glory I due to a problem with Milton Bradley, though I have chosen to refer to it by this name, as Quest for Glory I was designed, written, and programmed so that the entertaining aspects were removed. Therefore, it is my contention that Quest for Glory I: So You Want to be a Hero? and Hero's Quest I: So You Want to be a Hero? are not at all the same game.)
