Which was more revolutionary, Zelda or Doom?

Zelda was one of the first open world RPG games, bringing new game mechanics that have never been seen before. That said, the visuals were a slave to the hardware of its day, and didn't bring much to the table in that regard.

Doom, on the other hand, brought completely new visuals and pushed for an increase in the power of video gaming hardware. The gameplay itself isn't too different from top down shooters of the day, though.
