Learning a foreign language often includes making a lot of flash cards and just brutally memorizing their meanings. Well, now you can brutally memorize language vocabulary in a virtual world, with visual aids! Rob Howland's 3D Dictionary, or SanJiten, is a game where your mission is to study virtual objects and then correctly identify them later on in your target learning language.
It has all the elements one might expect from a standard non-educational video game including an item collection system (with hidden items), a player scoring system, a complex rewards system incorporating a game economy with unlockable content, and also some fun achievements.
Though they've already reached their Kickstarter goal, there's still a chance to buy the game/learning tool at a discount.
