Having been an HP fan from my early childhood, this game had been a long-awaited dream of mine – this is why Hogwarts Legacy is so disappointing.
Sure, the environments (especially the castle itself) are beautifully made (and the combat is kind of fun i guess), but it may be the game's only redeemable quality. Every second of it feels overly sanitized at best and just utterly boring at worst. The world outside of Hogwarts feels like a bloated mess and inherits the same flaws that plague a lot of mediocre open-world games — namely: hastily scattering around repetitive tasks and easy "puzzles" to make you feel like the world is more engaging than it actually is, rather than spending time designing a world in which exploration is its own reward. This game is essentially a straight line masquerading as a network; empty space punctuated by busywork.
NPCs are generally as charismatic and interesting as a wood plank, there's absolutely no nuance to how their dialogue is written. The overabundance of those wood planks only reinforces the feeling that you are, in fact, playing a video game. Everything and everyone around you feels soulless, and the player has very little agency. I mean yeah okay, being able to magically rotate a globe in a corridor by pressing E is cool and all, but besides that you have no influence on the people and events around you — you can't even jump over a f****ing banister if you want to! (There's no repercussion whatsoever to casting "unforgivable" curses inside the school though, so knock yourself out!)
Call me a purist, but I like my RPGs when they let me actually be a part of the world, instead of a Mary-Sue-type outside observer doomed to have pointless conversations with wood planks all day.
Also, who thought it would be a good idea for potions to be a waiting game? Why not, i don't know, letting the players actually brew the potions themselves for example? Even the bonus game on the Harry Potter 1 DVD had better gameplay than this.
tl;dr: one of the most sterilized, boring, frustrating, repetitive and un-immersive games i've played in a long time.
