Goodbye Eternity is the absolute best game in the genre. I'll be honest and say that I've played a bunch of other games in this genre. Just something that I do maybe once 3-4 months. Throughout past 9 years, I have yet to find anything as polished and well thought-out as Goodbye Eternity. The game has absolutely stunning visuals and a nice story with it's drama and comedy. Would absolutely recommend to try it out if you're into R18 games.
