Thanks for that extra context.The Steins;Gate anime does have some small details that would go over your head if you didn't read the Chaos;Head visual novel (ie Daru mentioning a friend he has that could help find the IBN 5100 which is from Chaos;Head), but it's not really detrimental to the experience. Same thing with Steins;Gate 0, there are small mentions and hints about the other games but it's fine. I think when it starts to become a issue is with games like Robotics;Notes and Chaos;Child. These games either have returning characters from previous titles or important lore/info that the game thinks you already know about from previous entries.
It makes sense to have those latter two titles mention which required titles offer required knowledge, but it feels a little silly to mention Chaos;Head as a source for recommended knowledge for Steins;Gate. I don't think small insignificant cameos are worth checking out another title out for. 😅
Consider this a small heads up for gimme_yuri_plz to not care too much about watching Chaos;Head before embarking on the wild trip that is Steins;Gate.
