Great news about Stein's Gate 0. I still haven't started playing the first game but I've watched the anime and the movie and I loved them. To be honest though, I'm not a fan of sequels to games that I thought the ending was great because it has a chance of ruining it like fuuka ruined Suzuka for me :p
S;GZero isn't a Sequel, is a alternate universe, kinda a spinoff... So You can like it or not, but the original ending keep being canon.
That twist plot on Fuuka, still doesn't make sense for me... kinda forced or improvised...
