I've posted about this before- I live in South Africa. My domestic worker started playing Angry Birds last year with my then two-year old. It was a hook that got her into computers, something that intimidated her until then. She got a computer for her family back home. A door was opened that was until then shut.
Deciding what "matters" is a trickier than we think.
Angry birds falls under none of the criticisms people make of zynga's output. It's a honest-to-goodness, (relatively) original and fun game. People play it because they like it, not simply because they need the dopamine hit.
Eh, it's a grinding game with intentional randomness added on top of a low-skill base for Skinner-box purposes.
It's not pay-to-win like Zynga games, but it is intentionally addictive to play.
