Battle for wesnoth is pretty good I think. Very simple and well designed IMO. I don't play it much myself anymore, but my son(12yrs) loves it. And so did I for a while.

It won't compare well to Dom3 or MoM because their values are very different. If I was to compare it to anything it would be warlords.

One of the wonderful things about Battle for wesnoth is that the community provides a vast set of languages, including swedish for example. So it's accessible for kids who don't speak english so well yet.
