It seems surprising that Microsoft even owns copyright in the works that are claimed.
"Tom Clancy's Splinter Cell: Conviction" is apparently a Ubisoft product, which is a publicly traded company distinct from Microsoft.
Copyright in "Lego Star Wars: The Complete Saga" is apparently held by LucasArts.
While they all appear to be Xbox 360 games, being a platform manufacturer doesn't usually mean you own the content produced for that platform. It is possible that the games linked against a Microsoft library, and are infringing against the Microsoft's rights in the library, but then the declaration needs to declare that "that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed" - which means that the allegation of what is being infringed (i.e. a library and not the entire work) should have matched the work Microsoft owned.
