One of the best text adventure games to date
Chaos;Head put us in the shoes of a MMO-addict in an adventure filled with mystery, conspiracy and delusional fantasies. Steins;Gate brings us another adventure in the same world, this time led by a protagonist that's got a bad, bad case of chu-ni-byou (role-playing as an imaginary character in real-life).
Time travel is at the heart of the story here, and while you'll recognize many of the elements from other books/flicks surrounding the issue, the impressive voice acting, solid script and art that matches the atmosphere extremely well combines into a gripping experience.
Frequent references to 2ch memes exist, as do sometimes overly complex physics theories are present as integral parts of the storyline. Not recommended for those unsure of their Japanese comprehension, but for the JP-fluent, this is a must-have.
