Unlike you, I have already learned a long time ago that we will never ever ever ever get any more games like BG1&2. The only thing we can get is this game right here using the latest ruleset, because people like the OP never actually asked WOTC for more AD&2 2.0 games.
Thanks for obsidian Entertainment and Owlcat games... Both made recent and awsome games based either on an adaptation of d&d ruleset (pillars of eternity) or on an actual version of the said rules (pathfinder kingmaker). Remember that neverwinter Nights was well received by BG fans even if the game were not based on aD&D 2.0, so were Pillars and Pathfinder.
Therefor, speaking about rules and mechanics i truly think that both studios would have been better candidates than Larian studio to design BG3. Anyway they'll continue releasing games in the future close to what they already made.
I am 100% convinced this is yet another troll post about how this is 'DOS 3'. I'm not going to go, point by point, on how you are wrong, so I'll be concise:
1) Everything you said a bout the rules is wrong. There are no 'BG rules'. It's D&D Rules. And this is 5E. Anyone can multiclass. Spells can miss. D&D is turn based. Clerics have offensive spells.
2) 'Miss' in combat is a catch-all term. Either your spell failed because they rolled to resist, or your ranged touch spell failed to hit their armor class, or your attack failed to hit their armor class. Etc. Any time your offense attack fails to do damage, it's a 'Miss'.
3) You can jump in D&D. You can become Crouching Tiger/Hidden Dragon. There's the Jump spell, and there's feats to jump higher. Being a Monk, you can, if you build properly, get as high as 90 feet in the air. This is not a 'pure DOS system'.
4) This game is based on D&D 5E. Casters can wear heavy armor if they have heavy armor proficiency. That is in the 5E rules.
5) Critical misses are a thing. So are critical hits.
6) The 'law, lore, and world' is Baldur's gate. It's the land of Faerun (in the Forgotten Realms). It's the city of Baldur's Gate. It's the rules of D&D. BG 1 & 2 are canon events in BG3.
7) We only have the evil party members so far. There are good party members. And there's no real alignment system in D&D anymore. That system was too rigid. Plus, good or evil; you have to work together to not have your brain and soul devoured by a baby mindflayer.
I could go on but the more I read your post, the more I'm convinced this is a bait post. This same stuff has been said, daily, for the past 8 months. And it's been wrong, for the past 8 months.
Being fan to the point you're extremely disapointed about the direction a game from your favorite license is taking is being "troll" ?
I'd say that replying to OP using words such as "troll" or the like with unfeigned disdain because you're a fan of the the studio that pushes the said direction, knowing that your pov is mostly shared here, is being troll and maybe more but i'll stop here.
Anyway D&D 5E would not be a problem if Larian were true to it. But they're taking huge liberties from it and are already starting to inject some DoS concepts and mechanics to it.
Here is an exemple from a thread posted on reddit that perfectly highlight what i'm saying :
"Mephit in 5e : Once per day, the mephit has a 25 percent chance of summoning 1d4 mephits of its kind. A summoned mephit appears in an unoccupied space within 60 feet of its summoner, acts as an ally of its summoner, and can't summon other mephits. It remains for 1 minute, until it or its summoner dies, or until its summoner dismisses it as an action."
Larian's interpretation of this, for all intents and purposes is this: "Once per day, the mephit has a 100 percent chance of summoning 1 mephit of its kind. A summoned mephit appears in an unoccupied space within 60 feet of its summoner, acts as an ally of its summoner, and can't summon other mephits."
And there's A LOT of exemple like that : minotaur, phasing spider, gnoll archers... But also about spells, and so on, and so on...
I'll be honest tho even Owlcat Games took liberties when they had to about Pathfinder Kingmaker, but Larian did more than a few necessary liberties they're modifying the DNA of D&D which brings the game close enough to DoS for people to see obvious similarities. No need to talk about their surface fetish...
