It's a clash of the titans today, as Game Politics discovered that Valve is suing Activision, with Activision threatening to countersue the Half-Life developer. Here's the thing: the lawsuit itself actually stems from a 2002 cybercafé licensing dispute between Valve and Sierra, a publisher Activision inherited as part of the Vivendi merger last year.

Thus, this dispute is now Activision's problem. Valve is suing Activision for allegedly refusing to honor an April 6 court decision that should have settled the issue.

Activision says the decision awarded Valve too much money -- we're talking $2,391,932 vs. $1,967,796 -- and decided to write Valve a check for the lesser amount. Clearly, Valve isn't happy with this outcome, nor is Activision excited about Valve's decision to take the situation to court, which may prompt them to countersue.

This all begs the question: when's the last time you played Counter-Stike in a cybercafé?!
