It's easy to forget these days, but Rockstar was once better known than Red Dead Redemption and Grand Theft Auto. GTA has been the studio's best-selling franchise for quite some time, but more experimental projects like Manhunt and Bully have allowed it to take bigger risks and often showcase some of the developer's boldest ideas. With the latter now a whopping 18 years old, the lack of this series, ironically aimed at teenagers, is especially heartbreaking.
