Diablo is getting a board game and tabletop RPG that will “continue the lore and story” of the video games

In this case I'd actually not mind that much, since D&D5e and Diablo both are pretty much the same genre (High Fantasy with a lot of fireballs). Maybe slice all HP in half to make it a bit more lethal on both sides, but that's it.
It's way worse for stuff like "Adventures in Middle-Earth" and "Beneath the Monolith". Like, how? Those genres aren't remotely the same.
