The CloudWorks is something akin this VLN in the UK. Setup by JISC (UK), it is a place to share, find and discuss learning and teaching ideas and experiences. The link is to the results of a search on the word game. I haven't had a chance to check the quality of the resource. There is a somewhat low signal to noise ratio, with a huge number of pages and only a limited number of gems. But the UK, and more specifically Scotland, is known for great use of games to support learning.
