Private externals for competitive games can rake in a LOT of money. Its also high stakes because of the kernel-level anticheats these days, but being private makes it slightly easier. Public externals bypass methods are patched pretty quickly. Make something that's interesting to you, and if you like that side of engineering (reversing, bypassing ac's, etc), it's definitely a way to make a lot of money. I know some people doing it for rust (the game) that make a killing.
