And it's looking great so far.
I'm a 90's gamer so no-hand holding is fine by me. I managed to beat Elden Ring and while it's an action game, the stats/classes/spell mgmt/gears/debuff/buffs are pretty damn deep. I mean,
look at all this in Elden Ring.
BG3 throws lot at you, but it tries to explain a lot too. And so far, the stats aren't deeper than Elden Ring. ER has another added complexity of weapon-specific scaling at across multiple attributes at different rates; each weapons all come with specific movesets for every light/heavy attack/jump attack/roll attack/etc
and each weapon come with a special skill too
and/or assign other skills to the weapon. We haven't even gotten to enchanting or buffing the weapons. Also it has tons of spells across all attributes.
So far... in terms of 'complexity and depth', it's not beating Elden Ring yet (all the weapons / armor / diff combo movesets / guarding / stance breaking / timed parry / all the ridiculous buffs/debuffs/ all the stats/attributes/etc). I'm excited to keep playing BG3.
td;lr - action rpgs got complex enough that CRPG isn't that much of a drastic change.
