There is another game that did it right.
I tried the kickstarter trial version of Solasta: crown of the magister of the french studio Tactical adventures, and they made a very good job too. You cannot play that version anymore, they erase it after the kickstarter because they are improving it and din´t want to show an old version of the gameplay, but it gave me hope about the game.
They have actions, reactions, the shield spell, shield protect, etc... and you play in 3d, with jumps, high ground, feather spell too... all the features of the few classes you have available in the trial version (You also play low level characters) but you had almost everything you can find in the a PNP game.
I agree with the OP, the gameplay showed a lot of things you want to see in a videogame version of D&D5e. I missed some (like reactions, etc) but I hope the devs will improve it in during the alpha period.
