I remembered hearing about a whole genre of video gaming that was truly focussed on learning; not just basic math facts, but highly intricate concepts that include college and higher level science content with real life importance (e.g. curing cancer).
Here is a piece that was featured on NPR; To The Best of Our Knowledge, which gives a bigger picture view of this type of gaming (along with some other views into gaming culture).
There is a whole world of game creators that have a very specific goal of engaged learning via a video game approach. Below are links to several of these creators.
Most of the sites give further context to the gaming as learning theory, blogs and articles related to the topic, along with an opportunity to try out some of the games (I myself found myself getting into FiLAMENTGAMES "CITIZEN SCIENCE" game..Citizen Science is an adventure game that teaches scientific literacy and limnology.),
Happy Exploring/Gaming/Learning!
