Global Agenda is a third-person shooter released early this month. I finally got a chance to check it out and was surprised that it encorporates a good deal of OSG mentality. In this video describing the Conquest package, the designer could very well be talking about a Travian alliance planning their war. Similar to Erepublik though, each player only controls one character and only by joining with others do you form a whole army.
Hah, and this Gobal Agenda: No Elves video is great:
Anyway, it will be interesting to see what other genre’s the MMO Strategy gameplay works its way into in the future.
