Saints Row was awesome and one of the better game franchises of the Seventh Generation of Consoles.
Saints Row 4 was kind of a mess and the superpowers made a lot of the gameplay mainstays utterly pointless, but I think part of what limited SR4's potential was the deadline of trying to release it before Grand Theft Auto V came out and then you had the utter shitshow that was Gat Out of Hell, which killed the franchise.
Deep Silver tried to bring it back via a stealth reboot in Agents of Mayhem, but that game was awful as well.
I'm hoping THQ Nordic can get a hold of it and reboot the series completely, maybe do an overhauled remake of the first game?
