So there’s this Chiyomaru Shikura interview about S;G Elite (Japanese), but I actually found the stuff he said about the Steins;Gate 0 anime the most interesting:

-The anime is turning out to be more interesting than the game

-The VN has several routes, but in the anime, they’ve been restructured into a single route

-In the anime, Okabe isn’t quite as gloomy as he was at the beginning of the game

-Even people who have played 0 should be able to enjoy the anime as though it were a new work
