From early play it will be better than BotW. More to do, better story, wider variety of enemies, dungeons. The core gameplay loop is much the same though. Shrines, Koroks, Memories, beat a camp, get a chest, map towers. The opening sequence is pretty much Great Plateau 2.0. I’m not seeing a mask equivalent, or a three day cycle equivalent, that made MM so different from OoT despite sharing the same engine. There’s the Zonai gear and wider exploration. But I still think that’s an expansion of what we saw in BotW, rather than entirely new forumula.
That sounds probably a bit negative- I‘ve very much enjoyed what I’ve played so far, and expect to throughly enjoy the rest of the game. A curious praise is that it’s kind of hard to see why anyone would replay BotW after this.
Ultimately, I’d still like the next main game to go back to a more traditional item based Zelda, with Pieces of Heart, rupee’s under shrubs and pottery, dungeons, with a new core gameplay feature (equivalent to sailing, masks, Wolf Link, flying etc).
