Spencer declined to comment on whether it had held talks with Electronics Arts on such a move.

Last year, Electronic Arts, the publisher of popular titles like "Madden" football, unsuccessfully pursued a buyout of rival video game company Take Two Interactive Software (TTWO.O). The Redwood City, California-based company, which has a market value of $6.5 billion, is frequently named by traders as a target for Walt Disney Co (DIS.N) and Time Warner Inc (TWX.N).
