Job Pico is an excellent example of what’s called the “Escape The Room” genre in online video games. I wrote about them in my recent TechLearning article, and how to use them as a language development activity.
It has great graphics, and provides lots of opportunities to learn new vocabulary in the process of playing the game. Students can use a Walkthrough to move step-by-step through the game to its finish.
I’ve placed the link with the nearly 200 other online games appropriate for English Language Learners on my Intermediate English page under Word and Video Games.
