Wow, people still remember these games! I can still play most of them on my DOSBox right now.
True Love 95 and Season of the Sakura were among the first eroge that I ever played, back in late high school early college.
Three Sisters' Story has Risa, one of my all-time favorite eroge girls. She checks all the boxes for me: highschooler, genki girl, short pink hair, masturbates often, calls the hero onii-chan. The scene where you fuck her by the school, I've fapped to it about a hundred million times.
I see some people talking about Runaway City, and I hate to be the bearer of bad news, but i hated Runaway City. It's the most tedious "click every option to proceed" gameplay you can imagine, and has a completely linear story so you have no choice of who to end up with (despite there being so many girls, you end up with the worst of them all). And the scene with the gamer girl is absolutely the stupidest thing I have ever seen in my life. Who the hell writes this stuff?
