Poptropica is an online video game from Pearson Education which, according to the Poptropica webpage, is developing additional games, too.

There are some English language development opportunities in the game, primarily when the player has to interact with different characters and choose which questions to ask.  However, I would have expected more educational value in a game from Pearson.

I’ve placed the link on my Intermediate English page under Word and Video Games.
