Oracle of Ages
Oracle of Seasons
Link's Awakening
A Link Between Worlds
Four Swords Adventures
If I ever pick up a 3DS, A Link Between Worlds is right at the top of my list. I regret not having played Four Swords Adventures; I still have my NGC, but I can't find a cheap, used copy of this online. If Nintendo offered a digital version for Wii U via the eShop, I would download it in a heartbeat. I own copies of Links Awakening and the Oracle games, but I just haven't invested the time in them yet. The games have definitely aged and it can be hard to commit...
