I’m currently thinking about what kind of update system I should use for my game. The Indigo Rose delta patcher allows you to create small patches that just update your PAK files. On the other hand the Unreal system requires you to either deliver a complete PAK with the updated content or create some complicated setup from which to create a PAK file with the same and a higher number where only the updated data is in the project before baking.
I would be grateful for any advice here by people who have done the one or the other
