You'd be suprised what games accidentally ship. I've seen everything from pdbs to unoptimized debug builds accidentally included. If you don't make those mistakes, you might still have std::type_info (or custom equivalents) / RTTI info and __FILE__ / __LINE__ spam from macros, that can still sneak their way in.
Suppose you fix all that - the game still has a good chance of including 1 or more scripting languages. They may be included complete in their original unobufscated glory. Or the bytecode might include unstripped debug information. Or the C++ <-> script binding layer might still include unobfuscated string identifiers.
If you're clever, you'll rebrand this lack of obfuscation as being "mod friendly" ;)
