"But Sas, you're being hypocritical! You spend just as long hidden away with a book as I did hidden away with a game!" my game-devoted younger brother indignantly exclaims. True, I grant you. But I maintain that books give at least as much back as they take in. You learn about yourself, as well as about the world and time during which the book was written. You acquire more vocabulary and improve your writing skills. You can explore other cultures and places. They hone concentration and focus in a way that nothing else does. They sharpen memory. People with higher literacy levels are also three times more likely to be above the poverty level than those who don't read well. They deepen language-learning.
Video games might offer a tiny fraction of a few of those things, but you are removing yourself from the entire world. They are not connected to any reality, not even the author's, because too many people contributed for it to reveal anything about one person. They leech, with very little repayment for your attention.
