When Activision merged with Vivendi Games last year to form Activision Blizzard it took on all of the burdens of both companies. Now it appears one of Vivendi Games' issues has come back to light as Valve has now sued Activision Blizzard over an award it won back in 2002 from Vivendi Games.

Game Politics reports that in 2002, Valve won a judgement against Vivendi Games over licensing of Valve's games in cyber-cafes. The original amount was $2,391,932. However Activision Blizzard only got around to paying Valve last week and then it was only $1,967,796. Activision Blizzard's side felt that Valve had already been paid the remaining $424,136. Naturally Valve doesn't see it that way and the lawsuit was filed on Tuesday. Activision Blizzard is expected to countersue Valve.
