God of War: Ragnarok NoPSSDK (No PSN Mod) Download
This simple mod will remove the PSN (PlayStation Network) requirements to play the game on PC.
Unfortunately, this mod isn't compatible with other games that require a PSN account to play on PC. However, there's a good chance that there are other mods available on Nexus mods for those specific games. There's always someone out there trying to create workarounds for all of these stupid practices.
