Replaying Breath of the Wild is giving me some more insight as to what I want out of a sequel, I think.
Most people just focus on various weak points, some of which I agree on actually being weak points more than others, but I feel like I just want the next game to be an even bigger playground.
More enemies? Yeah, sure, but I don't need too many. The few enemies the game has are way more interesting than the entire wide collections of enemies in most other games, give me a handful of enemies that increase the "playground" feeling even further instead of just being setpieces and I'll be peachy. I think my assessment way back when the game first came out still sticks, give me three more enemies with their own personal weapon collections, food preferences, little hats you can wear to fool them, attack patterns, etc. and I'll be way happier than having 15 more enemies that kinda limply hop towards me and that's it.
More mechanics? Yeah sure, but I'd have the most fun by far if those new mechanics were tied into the same "could I do that?" feeling of the existing ones. Don't hand us a remote control robot to play with, let us tame the several species of wolves already there and adopt dogs and then expand on the existing Wolf Link AI to let woofers do things for us. Don't make a magic bloopledeblorp that turns things purple, just let us swim underwater and then create new avenues to explore from that.
Better writing? That'd be peachy, but I'd rather the story be told differently than the "let's railroad you from place to place" method people feel like is necessary. Make "show, don't tell" elements in the scenery of important locations, or unimportant locations for that matter. Make better written sidequests where it feels like you're actually being a hero going around saving the day instead of just an errand boy. I don't need all of it tied up in main quest related objectives, or even most of it. Because maybe I don't want to be the "hero of so and so specific epic unfolded in so and so specific way." Maybe I just wanna be a hero. Period.
Better dungeons? Again, sure but. . .full disclosure, I haven't played that much Zelda outside of BotW but what I have played of it makes me REALLY not want the franchise to go back to that, which is usually what people mean by "the dungeons are bad." Yeah, "bla bla Phantom Hourglass sucks", whatever, but. . .from what I've seen in video clips, comics etc. the overall format of "get an item, solve a long, bland, insultingly counter-immersive series of single-solution puzzles for no apparent reason and then fight a boss that's there just because" seems to hold up most of the time and yeah no thanks. The Shrines and Blights aren't visually distinct in the slightest but HELL at least they had a reason to be there! Why's there a giant spider? Why's there a fire wizard? I don't know! You don't know! Nobody knows! Who made these puzzles? What was the point of them? NOBODY KNOWS! Again, way back a couple of years ago my thought was "well maybe a fort taken over by a spider and turned into an elaborate spider nest that you have to burn through parts of would be cool." THAT's a reason for a place to have a spider boss! Maybe Ganon corrupted the spider! You can make it obvious, slap some Malice on it and say it got possessed. There's a reason!
. . .IDK, it came out as a pretty empty rant I've just been thinking about my differences in opinion from most people on where I want the game to go from here again.
