Edutainment title Code of Everand is the UK Department of Transport's effort to teach children road safety. The free MMO is targeted at 9-13 year olds and attempts to "encourage and reward" repetition of good behaviors for the real world. The premise is actually surprisingly clever, with players taking the role of the Pathfinders and endeavoring to safely cross "the Spirit Channels," which are glowing streams, laid out like roads filled with monsters.
On that note, if children from almost any other country play the game, remember to first look left before crossing the Spirit Channels and not right -- that's a free protip. Check out the Everand trailer after the break.
