Definitely Naughty Dog! Their track record speaks louder than bombs!!!

Nintendo's acquisition of Platinum Games that happened in a dream I had.

while i am not a Naughty Dog fan i won't lie when i say that Sony purchasing them is easily one of the best decisions that the playstation division has ever made.

i would also that Microsoft buying Bungie as a smart (and a just as equally dumb letting them go) since it was ultimately Halo that put Xbox on the map.

Gamefreak!

What do I win?

Sony = Naughty Dogs.

Nintendo = Game Freak (Pokemon).

Microsoft = I don't know, RARE maybe ? But purchased Halo I.P was a great idea :). The game is huge.

Off topic:

Sony own a lot of great studios though, like SCE Japan Studios, the studios that made/making Shadow of Collossus, Gravity Rush, thelastguardian, ICO, Demon's Soul & Bloodborne (co-produce with FromSoftware) or Sucker Punch with their inFAMOUS and Sly Cooper, but my personal favorite is Media Molecule, the creator of little big planet, Tereaway and of course DREAM.

Polyphony (gran turismo) is pretty decent as well.

Isn't gamefreak still an independent company?

In terms of great games produced, I'd rank the list as follows:

1) Retro (2000-present)

2) Bungie (2000-2007)

3) Naughty Dog (2001-present)

4) Monolith Soft (2007-present)

This is limited only to Nintendo, Sony, and Microsoft subsidiaries, and omits partnerships like Rare (1994-2001).
