Sony takes the most risks nowadays, that said I kinda feel "cold" to most of their IP for some reason, whereas Nintendo just seems to still have a certain magic.
If you could some how mix the two together, you'd have the perfect 1st party.
I like the Halo franchise, but the rest of MS' stuff I'm not thrilled about. They totally mismanaged Rare too.
