For me the only game that was ever good as episodic was Hitman 2016, but that was a really niche case where each level was like a whole game worth of content if you did most all of it (and 90% of it was really fun so not just filler), and repeating the level over and over was the point of the game so unless you have an ultra memory you will have a worse time moving between levels as you complete them because you won't make obscure connections you'd make if you stay in each level until its done.
So I can take episodic but only if its similar to that, where repetition is incentivised heavily and its extremely dense. He kind of already did that with Phantom Pain in that each mission is like its own self contained, mini-game you can replay over and over discovering new methods/content and come back to with new tools, etc.
It would be pretty cool to have something like Hitman with the dense levels but as they release more levels they introduce much bigger gameplay changes like in Phantom Pain and Death Stranding. In Hitman you can bypass parts of the level and kill from a distance which makes a big difference obviously, but going from being on foot in PP to, you can start in a tank or with stealth camo makes a bigger difference for the gameplay imo.
