Nah, there is a ton of games with more content, for female protag there is SlutEd, Fleeting Iris, Cupids Way, Fake AI, Girl Life, Inner Empire (not more content, but for a first release it's still a ton), Karryns Prison, Life Choices, Secret Taboo, Yorna, a fuckton of japanese games (for example anything from Clymenia is pure gold), Myriam, Third Crisis, Deegrees of Lewdity, Lisa, Noxian Nights, Defenestration, Miri's Corruption, Caliross, Raven Quest, The Winds Disciple just to name a few of what I liked personally.
If you take into consideration the development time, then it's above average. There were also many other good games, like Project Sage, but they are unfortunatelly abandoned.
