Educational games are always going to be pretty tough to review, as in the minds of most people the concept of learning and fun are mutually exclusive. If, however, you happen to be a fan of all things concerning the Earth, whether geography, wildlife, or nature in general, you may like the direction this particular game is running in. You’ll be able to challenge yourself solo, responding to multiple choice questions that range in difficulty, to see how well you know your stuff or play with some friends to see who the real expert in the group is. One oddity with the experience though is that with its quiz format it feels like its educational value is a bit at odds with its entertainment value. You’ll more likely do well in quizzes the more you already know, perhaps nullifying its value as an educational tool, but I’m not sure people seeking to know more would view this as their path to greater understanding. Still, if you enjoy the trivia quiz format, to play against friends or test yourself, it may be worthwhile.
