I have followed this game from basically it's inception and it has slowly become one of my favorite and most anticipated porn games available.
The setting of Defenestration combines characteristics of cyberpunk, Cold War era USSR, and post-nuclear in a way that is unique each on their own, but novel beyond measure when brought together. The story to back it up is intriguing and pulls the player in to want to learn more about both the setting and our heroine, Kira.
The game revolves heavily around transformation, utilizing a protagonist that has lost her memory, allowing the player to essentially choose who Kira is going to be, while still incorporating a backstory that feels well integrated and meaningful. The sheer variability in choices and optional/radiant events that take place creates an environment resulting in very few Kira's being the same, lending the game to enjoy a high replay value. Choices that the player makes have direct and impactful outcomes, both visually and systematically at a scale that I don't think I have ever seen in a porn game.
The art is the main way that Defenestration delivers on consequences of player action, and boy is it good. The direction that the dev has taken the art recently is highly consistent and unique, finding a happy medium between too cartoony/anime or too realistic. Each character has a charming and recognizable design that is evocative of the character's personality, with Kira being the epitome of customizability. You can play the intended spy fantasy with a lean and sophisticated Kira, go fully debaucherous and make Kira into a massive titted bimbo with DSLs plumped to the max and an ass that would make a Kardashian blush, or you can throw caution to the wind allowing the world to morph and modify Kira as you go.
That brings us to the vector of customizing and changing Kira, the porn events and the genres they occupy. Mind Control/Hypno underpins basically all of the events in the game, but Traditional Corruption is supported as an option to players hoping to not avoid or not engage with hypnosis. Both of these forms of corruption are used to satisfy a number of genres from Exhibitionism and Free Use to Hucow and Petplay. And for each of these genres, Defenestration shines as having some of the most satisfying porn events I have played to date. I don't even really like Hucow and lactation, yet the way this game integrates MC/Hypno/Corruption makes for some truly incredible and sexy events. I find myself actively looking forward to each genre that the dev team devotes time to.
The one major downside or criticism I find with this game is new content vs. old content. This being the dev's first porn game has led to a pretty stark contrast between quality of content available right at the beginning of the game compared to stuff that is being actively released. The old content is by no means bad or not pleasurable, it just isn't up to par with what is currently being released, in basically every facet (dialogue, grammar, porn render design and implementation, etc.)
The reason I have still elected to give Defenestration a five stars review, regardless of that caveat, is that even some of the "worst" content in the game is still leagues ahead of basically everything else occupying the same genres. Defenestration is a shining light for RPGM porn games and I am looking forward to see where it goes!
