Instead of buying out Larian should consider working together with some of the other indi studio's. You know pool resources.
Would think them and Daedalic could produce some awesome games (

Daedalic could definitely add some more story depth as well as the franchises they have available to them like Das Schwarze Auge. On top of that they are a publisher in Germany and so have connections/experience on that front as well. On the humor department they are also a good match with Larians humor vs Deponia or Harvey's new Eyes.
Don't think CDPR is a good fit with Larian, too different....
