There are two ways of looking at Little Mouse’s Encyclopedia. It is a children’s reference book that happens to be on the Xbox, and as such it’s lovely to leaf through for a few minutes. The watercolour art could happily grace the walls of a nursery, and that’s intended as a compliment. But while it does a great job of putting names to animals and plants, it does a less successful job of making you care about them, or telling a child anything that might stick. It could feasibly form an hour-long home-schooling lesson, but you’d struggle to make a curriculum out of it.
