I don't think Mario Odyssey or Zelda really modernised their genres. I think Mario was just a good game in a genre that as long been dormant so it kind of brought it into the modern age but as far as I can see it is just a good collectathon, nothing new to the genre.
Maybe BotW is new for its series but open world games have been pretty popular for a while, I suppose Zelda at least feels a little different from those though, not sure it modernised anything though.
I'm drawing a blank on games that have really made a big change except for one area of gaming, I think probably the most obvious revolutionary changes are coming from VR right now. In one year I've already been impressed by how different VR makes almost any game. I think it has its best times ahead even though I prefer traditional gaming, at least for now.
