Solasta- made by Tactical Adventures- is in fact tactical DND.   They put a story around it but it's really a sequence of DND battles one after the other.
BG 3 battles, at least in EA, are not as fun [DUCKS].  BG 3 is much more about production value, graphics and the story.  I'm incredibly excited but if I'm honest, I value the player characters and showcasing their talents in fights the most.  The story I often find myself space barring my way thru.  I don't want that to be true- I wish I was a story person but it's still hard to get into a store from a video game for me.  
Maybe with release- that will change for me.  I hope so!
