This is Wade's opinion. If there is anything worthwhile about the real world that he's so dissatisfied with, he doesn't share it with us. But come on, there must be something redeemable.

This is Wade's philosophy. As someone who doesn't believe in organized religion, it makes sense that Wade is unconsciously searching for another form of immortality: heroism, which he finds online.

Even though Wade is miserable in his aunt's trailer, he's able to escape and feel safe inside the world of a videogame. Home is where the (virtual) heart is, we guess.
