Yeah that’s fair, and im not defending the practice, it just made me think of some games that Ive seen that have multiple executables, usually with an inbuilt launcher that i have to bypass. Or when games used to come with a dx11 and dx12 executable. Personally i find that in itself super sloppy and annoying as well, but it makes a kind of lazy sense to just apply it to all the game files, in that its just one less thing to have to change if you make an alteration to the name of the executable file or add a new executable for whatever reason. Just one less possible failure point. But yeah I can see how its definitely not best practice.
The conspiracist in me wonders if this is intentional as the result of a deal with other publishers. Maybe its just that ‘the devs didnt get around to it’ but honestly with how simple it should be to release things on GOG i more wonder if it isnt suppression.
