Dan is very talented game developer/writer, undoubtedly. I loved his games from og Mafia to KCD, where he has a strong vision and follows it no matter what, which puts a soul to these games.

But other than that? Oh boy, he's such a difficult person, aka an asshole to the max. Hateful, narcissistic mr knowitall who spits conspiracy shit. And everyone who oppose him gets banned on his platforms, which earned him nickname Ban/Baniel Vavra (instead of Dan/Daniel).
