Look at where the interests come from! Usually they come from being ostracized and low-ranking as a kid. The Game of Life—competing for social status points, mating and so on—is generally the most exciting one plain simply because it is REAL. Those who lose it, being ostracized, dominated, bullied etc. take refugee in fantasy or intellectual interests. It is both an escapism and a way to rebuild the shattered ego, by claiming to be better than those by having more smarter or refined interests.
