Well then you should probably articulate yourself a bit better ^.^
Clearly just the presence of selectable classes/races and a fantasy setting with magic are not the full definition of what makes a game feel like D&D for you, or that incredibly broad spectrum of games across multitudes of genres that I mentioned would indeed meet that standard; since D:os2 didn't make it for you, but BG3 is, yet Solasta does not... but SCL does... I'm actually deeply curious about what it is that makes a game feel like D&D for you, because that's got to be a pretty peculiar combination of elements, and fairly unusual. I say this with no malice or ill-intent, truly; if BG3 as it is scratches that itch for you, then I've no ill-will for you over it - but I am truly curious about how it can, amidst that other selection of yes and no discernments about other titles. Can you explain your perspective a bit more? What elements are necessary for you, and what detracts from achieving that feeling, for you, to arrive at such an odd juxtaposition?
That aside, this thread is about a proper reaction system - and a proper reaction system is one of the core backbones of how the mechanical game system functions in D&D 5e; it should not be a surprise to anyone that people who play 5e will, in large numbers, as they have done, voice that for them the game is not managing to really feel like the game system it advertises as being 'the definitive video game representation of', and upon which advertising their purchase may have been predicated.
Since you do not and have not played 5e, I'd ask that you cede you opinion of whether or not it lives up to that acceptably enough to folks who do; you don't know whether it does or not, and you have no means to gauge such an opinion meaningfully. Others do.
BG3, in its present state, does not feel like an adequate representation of playing D&D in a video game environment, to me. Not by a decently wide margin - not a huge gulf, by any means, but a decent margin short of the baseline mark.
