you said
But it's not about making porn, it's about making money, and college doesn't mean you will make money (or have a career you enjoy).
If Jackerman is making the money and enjoying the process of making it, then it is definitely more important than college.
If he completes the college course then takes 5-6 years to work on his Art/Games then there is a good chance many of these subjects he studied will become obsolete.
PS I am a big supporter of enriching your skills & knowledge BTW, but too many people think college is automatically better without considering the variables. Most important factor is what Jackermans ambitions are, and where his art stands in his priorities.
