The lethality of the world in 1&2 contributed to so many memorable moments in them, for me at least.
There’s something different about figuring out step by step how it is even possible to beat the enemy that wrecked your shit as soon as you walked into the room, versus grinding out a more typical battle. I’m not saying it’s better, or that BG3 has to be that way, but it is definitely a big part of this particular series for me.
For example, I have vivid memories of running into mind flayers, and fights with certain dragons, and the demogorgon, and Kangaxx, and even the first time getting to the gnoll stronghold.
