I was amazed this much code fit on an optical disc! In particular, the granitic summer landscapes at the mountain resort are so geologically accurate that the textures appear to have been calculated from photographs.
I've found it educational to draw detailed maps and label regions often referred to in balloon hints and challenges. My young granddaughter has no problem, but I find switching controls from motorised vehicles to horses & people confusing. (Probably my age.)
Note that every scrap of information provided by the program in balloons, &c, has a meaning. Just traversing the landscape and mapping the resorts is interesting, relaxing, and useful.
