Matt Dinniman had this to say about that concern: "We talked about it. I think if you poll a lot of the hardcore, original fans of Dungeon Crawler Carl and said, 'Would you rather have live action or animated?', most people would say 'animated.' But if you poll the normies on the street [I'm booing too, reader], you'll get 80%+ saying they want live action."

So they're trying to reach a bigger audience. I will say I am hopeful, Seth MacFarlane had some excessive CGI the Orville, and it actually looked decent. So hopefully we get good CGI in a live action Dungeon Crawler Carl.
