Is Konami a good example? If we are talking eye for an eye that would be Platinum, Square or Bandai imo.
Is Metal Gear not a big enough name for you? Kojima can either still work on new titles, while Metal Gear handed to a Sony studio, and that's 2 AAA games right there. How about Silent Hill that makes a lot of noise from the PT demo. Still nothing as big as Bethesda buy, but that's a 7.5billion price tag.
