I gotta say, usually I just treat the 'no sexual content'-stuff here like I treat decaf. If there's going to be flirting and sexual tension, but no actual sex, then the whole thing is just like an empty promise. Like decaf.
But I don't regret making an exception for Doki Doki Literature Club, though.
IMO the best visual novels out there are the ones that aren't quite what they seem to be at first glance. The ones that make you look twice at little details. The ones that make you ask questions. The ones where little things that seem off aren't just plot holes.
The ones that tell very different stories once you read between the lines.
Doki Doki Literature Club is definitely one of them. And even among VNs like that, this one is remarkably good. I remember how Myth from Circletempo had similarly clever storytelling - but I also thought that its characters kinda fell flat. But in Doki Doki Literature Club, the characters are just as good as the overall story - they're well-written, well-designed, and appealing. They really come to life.
Overall, I really recommend this VN, and I can't really name a single bad thing about it. Even without any sexual content, it fully deserves five stars (...and that's saying something when you consider what kind of site we're on right now)
One bit of advice, though - this is one of those games where there's little easter eggs in the game files. Finish the first route, then look in the game's main folder. (...I only found out myself because ren'py choked on a script and I had to restart the game)
