The installation under Windows XP was einwandffrei and complications - no idea why apparently not for others. Lego Chess is a chess learning program for children and making our two (5 and 7) a lot of fun. The lessons are useful based on each other, the individual games compensate through the animations, the absence of a "real" opponent. However, the difficulty increases a bit too slow, so that "too often" won. And annoying is the music tooting - at least for adult humans in the vicinity. High motivation when übern and long-term game fun by the animation from the Lego world. Who the 3D board is too confusing, which can switch to 2D view. Our kids get out quickly.
