No fun allowed? OoT was a great game at its time just as BotW is now. Sure in 20 years time BotW will look poor but that does not reduce the feelings it invoked.
Oh yes, I love OoT and Majora's Mask. But there's a time for everything. 1998 was the time for the template they defined in OoT being a 3D version of the AlttP template. It made the best out of the available machine. As game hardware progressed however, that template was outprogressed left and right, only Nintendo largely stuck to it right up to 2011.
I'm not sure how well BotW will hold up. Never having played 2D Zeldas before OoT, I find them fun puzzle games but too limited by their 2D template. Their world just gives me nothing. ALttP never caught me like any 3D Zelda did. It can't, as I've come to expect what modern open world RPGs do in terms of world building. Less openness feels outdated. Who knows? Maybe 10 years from now, I'll have the same sentiments about BotW. Likewise, the technical limitations of OoT to which the following 3D Zeldas up to BotW largely stuck, make its world completely outdated when playing the game today. As the game was designed around separately loaded small areas gated by item progression and Nintendo was never been less than extremely proficient at game design, it's still a great game. But not being able to leave the preset path and explore the world unless you have item X or because the hardware simply never allowed to model it has been shown to be an unnecessary concept by RPGs into he last decade. It still has merits to control story progression, but nowhere to the extend of previous Zeldas slavishly relying on it.
Nothing to say against stumbling across an old ruined temple deep in the forest and having a moody music set in when you explore it. But a whole lot to be said against asinine item constraints preventing you from entering the temple instead of just wandering into it, as well as asinine small key filler and block pushing puzzles in such a temple.
