I'm Commander Bigcokezero, and this is my favorite game on the site.
But seriously, it is my favorite H-game. There's nothing else that comes together quite so well. 4Min genuinely had a vision and fucking followed through with it.
Its inspired character writing, intense and branching choices, and bevy of intense sexual situations are why it deserves a straight 10/10 rating, despite a few drawbacks.
The beginning of the game has you terrorizing the countryside and acquiring harem members along the way. These characters are really what make the game great. Funny, pathetic, despicable, lovable, headpat-able, and so much more. They feel real. Your roleplay towards them feels satisfying in either moral direction. And the quality stays high as they evolve throughout the story.
As far as H-content, it's really the variety and intensity that makes it great. While there are a few kinks that are off limits, most of the time it's safe to say this game goes there. The only shaky part of the entire game is that the CGs have a wide variability in quality. Most are good, some aren't, and some are excellent. Most of the new ones are really great, and I suspect the lesser CGs will be repaved with excellent ones in time. However, as someone who normally views "great art" as the #1 most important aspect of any H-game, let me tell you that this does not at all detract from Ravager being the real deal. There were a few scenes and CGs that were so hot that they more than made up for the duds.
Edit: Many of these older CGs have been remade, so once again, don't let this stop you experiencing a great game
