“There were many challenges in implementing Steam Workshop functionality since the game was not originally designed to support modding.
Moreover, it looks like the game’s publisher, Deep Silver, had a few words to say about this new addition: Thanks to a dedicated modding community, Saints Row IV has now received official Steam Workshop support, which means that we’re likely to see quite a few interesting projects in the next few weeks. However, since the title did not provide proper mod support, it eventually faded into the background, only to make an appearance once more three years after it was released. While it’s true that Saints Row IV could not really hold a candle to Grand Theft Auto V, the game still enjoyed a warm reception, and it received its fair share of attention for a while.
