I don't own the GOG versions of Saints Row The Third, IV, and Gat out of Hell, but I want to know how much of the game's content and files are different.
Currently I know the following differences from various sources:
* For both SRTT and SRIV, menu entries for My Steelport features are removed from Main Menu, Image as Designed, and Wardrobe. (
Source: SRTT GOG My Steelport Enabler) Likely due to different menu files, my "
Menu Theme Override" mod do not work in GOG version.
* Functions for My Steelport is partially disabled in SRTT. The executable file is modified so the game thinks it's always offline.
* Functions for My Steelport is removed almost completely from the executable file in SRIV.
* For SRIV, Camera option in HUB does remain. Trying to access it without GOG Galaxy gives us an error message not present on Steam release: "You must Go Online in GOG Galaxy to use this feature or re-connect to the Internet to use this feature." (
Source: Saints Row Wiki at FANDOM) But if you have GOG Galaxy, the game gives a different error "***_***_PRIV_DENIED". (

* SRTT has no online play, LAN only. (
Source: SRTT GOG Store Page "NOTE: Multiplayer is available only through a LAN connection")
* SRIV and GOOH have online play, but require GOG Galaxy for doing so and can only play with other GOG users.
* SRTT's LAN play can only be played with another GOG copy. For SRIV, LAN play between GOG and Steam versions are possible but might cause issues. (

Do all the Saints Row games have LAN coop?")
* SRTT is missing Achievements. Other games have Achievements via GOG Galaxy.
* In SRTT, DLCs can be blocked by editing "gog.ini" or using a tool called "DLC Blocker". (

Things I don't know:
* How many of vpp_pc files are different from their Steam counterpart? I know files related to menus are probably different, but what about others?
* Is Camera option still present, sitting uselessly in SRTT?
* How much of text has been modifed? I know SRIV has a new error message for Camera, but what others?
* Is it possible to block DLCs in SRIV? If so, how?
FYI, Saints Row 2 is 100% identical between Steam and GOG except the executable file. GOG version's exe file has no DRM and added 30FPS limit.
