The dude's opinion IS academically of more value simply on the basis of his experience, and his subject-matter expertise.
Think of it this way: Who do you think a company is going to recruit?
A. A lead dev of a majorly popular online MOBA/RPG game?
B. Random dweeb from some online forums who has a logically coherent theory about game design?
It would be ethically and moraly wrong to recruit person "B" in this situation... It's obvious that you're a student of the exact sciences, but unknowledgable about applied social sciences...
