Ue Serialization Savegames

This one walks you through Unreal's save game plumbing from the ground up. You get USaveGame basics with proper UPROPERTY tagging, ULocalPlayerSaveGame for version migrations in UE5+, and FArchive patterns when you need binary control or compression. The step-by-step format forces you to declare your versioning strategy and slot management upfront, which honestly saves you from the usual mess when your first patch breaks everyone's saves. It covers async paths, FSoftObjectPath for asset references, and has working snippets for FMemoryWriter, FBufferArchive, and the compressed proxies. If you're past the tutorial phase and need a real persistence layer that won't explode in production, this handles the annoying parts.
