Googlemaps RISK?
“ZenChi has created his latest Google Maps API project; The popular board game RISK on Google Maps! While Zen develops a human multi-player option in his next version, you can play a hot-seat game right now with others.”
I have no idea how to play RISK but I remember my brother spending days playing it with his mates, or maybe it just seemed like days to a very impatient person like me?
