As of late, Hideo Kojima actually. Death Stranding looks bizarre in story and rather mundane as a game, but I know from experience that Kojima usually delivers on what he says, so I'm actually still excited for this game and his new studio.

Speaking of individual designers, I still have a serious soft spot for Hironobu Sakaguchi. While I would never say all of his works are the "greatest things ever!" I would say I've yet to play something he's worked on that I didn't enjoy. It will be interesting to see what this new IP he's working on will be. Though like many people out there, I'd really love to see him come back to working on console gaming.
