The release and subsequent rise to fame of Rockstar Games' Grand Theft Auto series paved the way for other open-world action-adventure games with similar likeness. One of those such games was Volition's Saints Row series.
However, while the first two were admittedly very GTA-like, subsequent entries purposely deviated. The developers focused more on over-the-top gameplay, popular culture references, and parodic humor that's not above making fun of itself.
While the Saints Row series has become one of the best-selling video game franchises of all time, Volition hasn't released a new full entry since 2013's Saints Row IV.
With that said, there've been rumors going around in recent years that a new Saints Row game is in development. The most recent information even suggests that Volition is going to announce the new Saints Row game at Gamescom 2021 in late August.
