Worst Plot: Adventure of Link. It had no real originality in it! You awaken the sleeping princess, not save the about-to-die princess!
Best Storyline: Ocarina of Time. This game sets everything up. It explains how the Triforce got there, how the Triforce was split, the sages who locked up Ganon, and the reconstruction of Hyrule/Imprisioning War.
The origional did have a plot. If you stayed at the title screen, it would tell you a story in 8-bit font! It would say that Ganon had the Triforce of Power and was going after the Triforce of Wisdom. Zelda split the Triforce of Wisdom to prevent Ganon from getting it, but now you are stuck with getting the pieces and smiting Ganon. :nerd:
