So from what I've....heard.....No major spoilers.
This game is basically Breath of the Wild 2. Starts the same way as BotW, you run around a small area, unlock your core gimmick abilities, finish that area then you can explore the world. World is relatively the same as last time, but a little remixed because of the event that happens at the start of the game + the sky islands they've added, Nintendo did a neat trick to keep the islands as far as humanly possible from Hyrule on the ground so that you don't have performance issues regardless of where you are.
Most of BotW's gameplay gimmicks are here, weapon destruction, food making, the fun environmental gimmicks with fire and explosions. They actually doubled down on weapon destruction because I swear...from what I've seen from the leaks that I totally haven't played, you go through weapons 2x faster then you did in BotW1.
I like the build and stick gimmick power, but I like it more for simple puzzles as opposed to making vehicles to get around. The game kind of encourages you to make things by leaving piles of building materials littered around the map. Sometimes for a specific puzzle, other times just to build things you might have fun building, I think this is where my older brain kicks in and I don't really see the fun in that, I'm sure kids that love Minecraft and junk will love this gimmick though.
Anything else I have to say about it is a bit spoilery, so I'll shut up until the rest of you join in in about a week.
