I ended up reading Steins;Gate, but after I had finished it, I wasn't sure which one I should read next. When searching for Steins;Gate cartoons, I found all these different parts and I started reading Bokan no Rellion and it looks like it's the same story, but from a different character's perspective. So what about the other parts? Are they the same story too or are they sequels and is there a specific order I should use to get the most out of the story?

* Steins;Gate
* Steins;Gate: Bōkan no Rebellion
* Steins;Gate: Onshu no Braunian Motion
* Steins;Gate: Shijō Saikyō no Slight Fever
* Steins;Gate: Hiyoku Renri no Sweets Honey
* Steins;Gate: Aishin Meizu no Babel
* Steins;Gate!
