What I don't get is why 5e doesn't work for video games, or rather why people think it doesn't.
I can create a map in Tabletop simulator and play with players and DM an entire campaign using full blown TT rules. With the map, the players can move their avatars and use full rules just fine.
This is what I was expecting with BG3 except instead of the DM moving monsters, the computer does.
For combat, I don't see why this isn't doable. It works. I've done it. Video game pawns and maps. So why don't those rules translate exactly?
