It's easy to forget these days, but Rockstar was once known for more than just Red Dead Redemption and Grand Theft Auto. While GTA has been the studio's best-selling franchise for quite some time, more experimental projects like Manhunt and Bully have allowed for greater risk-taking and growth, often showcasing developers' bolder ideas. With the latter now having turned eighteen, the absence of this ironically teen-focused series is particularly poignant.
