What are the advantages to compiling Unreal Engine from source?

[and-rad]

1. You can make changes to the UE source code.
2. You can leave out bits that you don’t need which can reduce resource consumption and limit possible sources for bugs.
3. You can pull in features and fixes from old/new engine versions while still staying on the version you’re currently using.
