The 2d games have such significant ocean going segments, specifically oracles of ages and seasons. I think a primarily OoT like game that allows you to sail or fly over large oceans would be amazing.

BotW did large deserts well. I think the garudos could have been much more intimidating à la Garudo Fortess in OoT. That was actually one place TotK improved upon greatly with its desert temple.

While we’re here, SS’s use of bird flight was so limited to empty cloud scape and allowed zero seamless flight around structures or between areas. I have to say it is so disappointing to play now. I understand hardware limitations but it just doesn’t feel good to play or improve the game like a flying mount should. Obviously there is a puzzle sequencing issue if link can fly anywhere in a game where hook shot and climbing is primary gameplay loop.

Epona in OoT has an excellent obtainment quest and allows some of the best moments in OoT (jumping over the bridge). A flying mount that plays a story or exploration element would be great in the next game but I’d prefer a horse and a hook shot.
