I plan on completing Link's Awakening on the Game & Watch and heading back to The Legend of Zelda and completing it again too. I've never completed The Adventures of Link and wonder if I'll finally do it on the Game & Watch?

Afterward check out the three article series Nintendo created on all the secrets they've stuffed the Zelda Game & Watch with. Some of these were included in the original games and some are completely new to the Watch system.
