In my opinion, Breath of the Wild ISN'T "loads of fun". It's barely even a Legend of Zelda game, really; it's an experiment, seeing what it'd be like in an open world rather than the usual closed world.
Except that they ruined it by adding needless survival elements (stamina, weapon and shield fragility, temperature) and by making the game far too repetitive and bland (shrines, Korok seeds), along with crippling the story by making it so the final boss could be challenged at any time.
I've played through more enjoyable open-world games - Skyrim, Assassin's Creed Origins and Odyssey (Origins was better), Batman: Arkham Knight, Watch_Dogs - and whilst I never finished most of them (only Arkham Knight) I still did enjoy them due to how they weren't this repetitive and didn't have needless survival mechanics. Sure, Skyrim did have stamina, which is a flaw, but its weapons were indestructible and I wasn't bothered by temperature changes; the other games had none of these.
I play Legend of Zelda for its story, for its world, and for its gameplay; Breath of the Wild fails at all three, whilst previous titles (Twilight Princess, The Wind Waker, A Link Between Worlds, Majora's Mask 3D, Link's Awakening) succeeded. I'd much rather play through, and recommend, these five over Breath of the Wild.
