Google recently announced that it would add a gaming element to its Google+ social network. Again following in Facebook’s footsteps, the move was seen as a direct effort to increase engagement by keeping users on the Google+ site for as long as possible. Google’s gaming efforts suffered a major setback this week, however, as at least two game makers began pulling titles from the site, The Wall Street Journal reports. EA-owned PopCap pulled multiple games including a version of its popular Bejeweled franchise, and Germany-based Wooga pulled three titles as well. Google’s Facebook competitor touts impressive user growth, but a recent study suggested that Google+ is a ghost town with very little user engagement.
