IIRC, when Interplay went tits up they liquidated their IPs to whoevever was buying. As in complete ownership of their IPs. I'm surprised that company still exists. It's probably just one angry guy who BOUGHT the name Interplay for forty seven cents and 3 cereal box tops.
And, as far as I care, Bethesda achieved success with the Fallout franchise that Interplay could never even hope to dream of.
