So my opinion that the ruleset, thematic elements, and setting, are much more main and centre in the series... Is somehow less valid than your opinion that everything is about this one set of combat mechanics and literally nothing else matters?
(Because, this is not a strawman from me, you have literally said that BG3 is nothing like the previous one despite sharing all of those elements and only really having that one difference that we know about so far, so not only are you now contradicting yourself by saying the game is a sum of all it's parts, you're actively saying the opposite at every opportunity.)
And, that argument is not relevant to any of the points WE'RE making in THIS thread, so bringing it up and debunking it is still a strawman in the context of THIS argument.
Look, you're being an obsessive, entitled prat. Chill out or piss off. The devs don't have to make "Literally just baldur's gate 2 again but with modern gen graphics", they were given creative freedom from WotC and at every turn as far as I can tell they're taking the responsibility of that role seriously.
So what if their combat is a little less evocative of BG if they're living up to the series' other core concepts even more vividly, particularly when it comes to evoking D&D in video game form; (If you'd actually watched the entire video you'd see that even the introductory trap in the first dungeon is much more evocative of something you'd see in D&D than almost anything that'd come before. But then looking at your comments thus far if you'd watched the whole video you'd instead be whining about how the pregen vampire character is gay and that magically ruins the game somehow. (And yes perhaps that's an ad-hom but you're fucking exhausting to talk to so my patience is spent at this point.))
"Resemblance of the previous games" is not a linear measure based solely on whether the combat system is the same. It's a complex array of factors and they made the decision to emphasise some at the expense of others because they felt it'd make for a better final product, and until you have actually played the finished game you have no right to judge that.
