It's pretty meaningless, sadly.
Unless the German government is willing to find dozens to hundreds of millions of dollars of funding, it's just wishful thinking. Like, yeah, that'd be nice.
The reality is that, as far as I am aware, there are no teams with real recent CRPG experience currently operating in Germany, and I'm not sure there are even any studios with RPG experience left, thanks in part to the ultra-scumbags at Embracer buying up basically every AA developer in Europe, then screwing up their Saudi money deal, which they were 100% relying on, and having to shutter the vast majority of the AA. For example, Piranha Bytes, for made the Gothic, Risen, and Elex games is gone - everyone got let go.
So how exactly is this going to happen? German has a games industry, but it's mostly AA strategy titles or mobile gaming.
With who? There are no studios in Germany who even in a position where they could starting hiring to work on a D&D CRPG and have any realistic expectation of succeeding.
