Nobody really expects RPG's to be as big and deep as BG3, they just want a complete game that works without shitty microtransactions everywhere and always online for no reason. Plus, having interesting characters and storylines, quests that can be solved in more than one way, and gameplay that's actually formed by taking player feedback and listening to it is what people reacted well to, among other things. Baldur's Gate 3 doesn't even have Denuvo!
If there's one thing that I hope competitors learn from Larian and BG3, it's that respecting your players and giving them what they want leads to success. Similar to Elden Ring and from software, like that video mentioned. Now compare BG3 to Diablo 4 and Immortal, or the upcoming Starfield and you'll see why people love it. It's not about specs or scope, it's about designing a game to be actually FUN.
