There is nothing BG3 does that is remotely extraordinary
The environmental reactivity isn't really rivalled by any other RPG, it almost feels like an isometric immersive sims in some areas. The sheer number of non-combat applications for magic in this game is extraordinary, as is the mechanical freedom you're offered in combat.
Want to shrink yourself so your Barbarian can throw you at an enemy? Want to create a wall of fire then use Turn Undead to force everyone into it? Want to use Gust of Wind to just blow half the enemy force into a chasm? You can!!
The goblin camp is what really sold me on the game in my first playthrough. In most other RPGs it would have been a case of just killing everyone or just speech checking everyone, but in BG3 I broke into their store room by going through a crack in the wall that only a shrunk version of myself could fit in, stole their supply of smokepowder barrels, hid them behind the throne of the bad guy, then split the party into two, having three of us travel outside and one (Astarion) stay inside and climb up to the rafters.
Astarion hurled a fireball at the barrels and the bad guy was blasted to death, then Astarion passed sneak checks to creep out across the rafters while the base went alert below. The rest of the team knocked out a couple of the guards on the outside in order to smash down a weak wall which gave an opening onto the rafters where Astarion was hiding, letting him rejoin the rest of us and flee before the goblin guards could find us.
It's an absolutely great experience and one of the closest I've ever seen a cRPG come to the "let's try
this shitty fucking idea" approach of TTRPGs. This, more than anything, is what people are buzzing about, I think.
I take it you never discovered that he'd basically brainwashed and raped Stelmane and wanted to do the same to you.
I never got that scene! For my own playthrough though, based on what I did know: I could tolerate his obvious manipulation of the player character; the tadpole situation is dire enough that being used as a chess piece in his dumb masterplan to destroy the brain is ostensibly the best bet you have to survive (and you do, in the end).
Next time I play it I'll fully side with Orpheus and see what happens. I fucking hate Gith though, especially Voss. Being able to stomp his face in was the best part of refusing to free Orpheus.
