I suspect it's giving G/R somewhat short shrift to describe their contributions so dismissively -- those "feelies" were part and parcel of Infocom's charm and reputation. The agency was, AFAICT, a huge part of Infocom's marketing, and titles are absolutely within a marketing department's purvey. (And I suspect they were not working on anything resembling full-page ads for furniture sales and TV commercial for used car dealers; that's not the sort of thing that ad agencies at that level do!)
