Real Understanding Of Serial Generation

I am just wondering how many people here actually take the time to reverse the serial protection and understand it or do you just grab the code section to create a keygen or obviously the simple old bypassing schemes (74 to EB etc.. xor eax, eax and so on)...

I am in the middle of reversing a serial protection I messed with 1 1/2 years ago which I myself have usually rarely done and I am finding it frustrating but quite refreshing at the same time! Besides, it will just broaden my 25 years of messing with code.
