An Interplay spokesman was not immediately available for comment.
According to the suit, on Aug. 6 and 7, Interplay sent letters to VU Games claiming VUG was in breach of a distribution agreement between the two from August 2002. Those letters, VUG said, claimed it had withheld payments from Interplay and improperly deducted from a reserve fund.
VUG said it sent letters denying those claims, but on Sept. 16, it said, Interplay sent a letter terminating the agreement.
The suit asks for a determination of each side's obligations under the distribution deal, damages, interest and an injunction preventing Interplay from gaining another distribution deal with a different company.
