Well, Stas, it's always a pleasure to argue with you. In your
comparison, you miss one major point for this project: i18n.

Being based on GTK and using the GTK widget plus pango, it makes it easy
to build an outstanding application that works worldwide. On the
GCompris side, we always have preferred to support more country and more
children than to propose cute animation to a few of them. As for
supporting animation, it's nice to have some but frankly, for the kind
of application we are building, it's not a top priority.
