Hello everyone, I am new to this site but can anyone suggest a game that has the best build up or lead into sex? I hate games where the girl just instantly falls in love with you. Thanks for the help.
Acting Lessons and Babysitter probably have the best build up currently, at least for the western game market. They're the two romance games that I think are written very well. Of course, it is correct that there are a lot of japanese VN that do a very good job of gradually introducing a romance, but that's what happens when an industry actually has funding.
Grisaia No Kajitsu is definitely a good choice if you want a long buildup, the common route alone is easily 20+ hours alone. Katawa Shoujo is fairly similar, though its a fair bit shorter.
