I don't know anything about this game or it's predecessors.
Is it just a fantasy RPG or what's the hype all about?
How is it different from other fantasy RPGs?
Diablo is like a fun action packed shooter. Like watching John Wick. You're there for the adrenaline.
BG3 is a deep story game with a LOT of choices, a lot of them can go into weird directions. Like watching Lord of the Rings. You're there to seethe a Elf throws the Dwarf.
