Hello I was playing Robocop Rogue City new game plus campaign and reached the ocp arms expo and gog galaxy said it couldn't sync after I exited the game because it is 204mb and gog limit is 200mb, can anyone tell me what I can do how to go about picking the data I want to keep and what to delete on gog galaxy for the game? so I can free up space?

Check your save files in Local App Data. Robocop Rogue City is supposed to only keep the latest 5 autosaves. If you look in the in-game Load Save screen, you'll only see the last 5 autosaves due to the fact that SaveIndex.sav only tracks those. However, if the files aren't deleted in your actual save folder, they can clog up space. I recommend deleting all your cloud saves in GOG manually via Manage Cloud Saves on your GOG account, then go into the folder and delete all but the latest 5 autosaves. Then play the game again and let GOG cloud saves sync and that problem should go away. I ran into that issue myself and this fixed it.
