The sad reality is they marketed it as a 5e DnD game but in the end what we will get is DOS:3 with some DnD mixed in. I dont see anything from Larian that suggests the contrary.
While I like DOS series, I was expecting a DnD game this time. I guess Solasta and Pathfinder(wich is basically 3.5 in another universe) will have to do it.
