This game is entirely inoffensive, much to its own detriment.
The premise is cool, but suffice it to say that both the movie and the show used it to greater effect. The plot as a whole is kind of boring, most characters are uninteresting, the dialogue is stilted, and the whole thing is riddled with grammatical errors. Nothing really grabbed me, I wasn't invested in the story at all and just kind of went through it because the pacing is kind enough to never linger too long on any one interaction.
The renders are decidedly average, nothing egregiously ugly but nothing that hasn't been seen before. I turned off the audio after the first cunnilingus scene since it had no moans and thus sounded like I was listening to a dog lapping up water.
Ultimately, I came away with the realization that I wouldn't be interested in this at all if it wasn't for the premise. The idea of an actually intelligent man as a main character is enticing; certainly a departure from the average bumbling teenager with a horsedick and a lucky streak. The problem is that the MC isn't actually that intelligent, certainly not a genius like NZT supposedly makes its users. As you play through the game you'll realize that instead of making the MC smarter, the drug made everyone else dumber. Every problem he solves has a fairly straightforward and instant solution, one your average person should come up with easily. Unless, of course, they were all dumbed down for the purpose of making the MC look smarter by comparison.
I truly appreciate that making a game, VN or not, is not easy, and I believe that with some major rewrites this one can be at least a good story; but as it stands right now there's no aspect of it that makes it worth playing.
