A Fallout MMO has been talked about since 2004, but Interplay was forced to sell off most of its licenses due to financial reasons. When Bethesda acquired the Fallout license, Interplay kept an exclusive Fallout MMO license, under certain conditions. Interplay's annual 10-K filing reveals that Bethesda might be trying to cash in on that, claiming that those "certain conditions," namely full production within 2 years and funding, have not been met, which would revert the MMO license back to Bethesda. Now it seems the Fallout 3 developer is following through as it has formally filed suit against Interplay for their inability to move forward with the MMO, but also for making digital distribution deals with GOG and Steam for its back catalog and repackaged products which have not been approved by Bethesda (thanks NMA).
