Nothing to do with education but it’s still worth a mention.
Now I don’t play many computer games these days – I just don’t have the time that most gsames require. For Portal, though, I made an exception.
Essentially a puzzle game the style is similar to a 3D shooter (it uses the Half Life engine and is made by the same people) but the only tool at your disposal is a ‘gun’ which can create two portals allowing you to reach otherwise inaccessable areas. The most spectacular portions of the game occur when you have to dive from a great height through a portal in the floor, only to emerge from another portal sideways at great speed (conservation of momentum and all that). It’s hard to describe but fantastic (if headache inducing) fun.
