@Sigment The one ";" I haven't seen yet XD A lot of people hate Chaos;Notes (for reasons I can only assume as 'not being Steins;Gate') but I actually quite enjoyed the anime ^-^ The psychological-mystery element really play key parts in the show (which I'm a sucker for), and the show never ceases to mind-fuck you at every corner possible :D My main criticism for it is that I would've liked the ending more had it stuck more to it's roots as a psychological mystery, but even so, I thought it was great :P I binged it in a single night XD
As for Steins;Gate... well, I'll late the Internet speak for me on that regard ;) never escaped my top 5, and likely never will; the show is a perfect combination of development, conflict, and resolution :3 The science in both shows sound somewhat credible, depending on your understanding of physics and/or psychology, but Steins;Gate focuses a lot more on time travel which leads to some interesting developments c: it may take you a bit to understand the concept of World Lines, but once you understand the science, everything will piece together quite nicely XD
That's my opinion of both - I don't think I spoiled anything ^-^ Oh, and if you think the first few episodes of Steins;Gate are boring, just remember it's a development stage and sets the scene :)
How's Robotics;Notes btw?
