博德之门3

Just get the expirience yourself, it is amazing

Never played BG 1 and 2, but I have played other D&D games before, such as Neverwinter Nights 1 and 2, loved NWN 1 (2 not so much) BG3 is essentially a heavily modified Original Sin 2, if you liked Larian's other RPGs and/or Dungeons & Dragons type stuff, you're most likely in for a good time. Unlike the first 2 BGs, this one is turned based, while the first 2 were group based cooldown combat (AKA MMO RPG-esque type combat). I feel like turn based works better for something with so much metaphorical (and literal) dice rolls. You can make a custom character, or you can pick a pre-existing unique character, which I recommend, since they come with their own unique personal sidequest, just like in Original Sin 2. I picked Karlach, because a demon woman that's constantly on fire because she has a hellfire engine up her ass, and recently escaped hell, was the most immediately interesting character to me. The other origin characters are pretty rad, though. All bangers. All the origin characters have tons of personality, and everyone even whispers when taking a command while in stealth. Speaking of stealth, feel free to pickpocket as many merchants as you want in turn based mode, take a few things, run away, exit turn based mode, and then quickly fast travel to evade prosecution, and then swindle the wares you stole back to them right after giving them a critical wedgie. STONKS. I've never seen a top-down RPG with such verticality, and the game even has a jump option (gasp). Not only does this give the game platforming, and the option to immediately explode your skeleton upon impact of a 50 foot drop, but it also gives you more options to avoid traps, on top of the Larian style put-a-potlid-on-a-trap-vent-to-block-it. Larian's talking animals are always a hoot, always make sure you have Speak to Animals active. This game is fairly well optimized (hint: It ran fairly well on low settings on a mid-ish range laptop. Buy this over STALKER 2 winky face ;)

I love Astarion. [I have played about 2 hours]

One of the best games to play ever!

The best game of its type, but I suspect you know that already.
