My mom will appreciate games rather than just decrying their "destructive" and "pointless" nature. Took long enough.
Games have long been in the realm of explaining everything from economics to interesting visualizations of mathematical patterns (such as The Game of Life). However, outside of those who generally work in such spaces, and those who learn about them in connection with Computer Science/Mathematics/Economics degrees, very few people in the general public have ever fully appreciated games.
That has broken down a little with the release of Guitar Hero and other games that draw in the casual gamer with a sense of the familiar, but there are many who still see the vast majority of games (like GTA, Starcraft, and Half Life) as simple killing simulators. Great to see new mods that are pushing games into greater and greater (positive) exposure.
