I mean, I think the tech inside out should stay, in that sense. Imagine being able to play SNES, N64 or GBA Mario Kart online.
If I were a tech assistant, I would make Legend of Zelda: Oracle of Seasons and Oracle of Ages a two-player linked game. Imagine each player in a different country, but you can send each other items / weapons / money / rings to help you (except for the sword, harp and rod)
One game I would love this guy / Nintendo to make is for Legend of Zelda: Four Swords Adventures. This game really should have been created with an online multiplayer feature.
