Holy shit. And Forza and Gran Turismo..they both let you race with cars! How insane is that!
But seriously, it isn't a pattern. Just two games who have a few of the same features. Pretty much every western RPG let's you choose your sex (Jade Empire, KotOR, the Fables, The Elder Scrolls, Mass Effect, the list goes on), and your second point is another feature that a lot, a lót of western RPG's use these days. It's not more of a coincidence than that more and more games rely on a story to make their games immersive, or that racegames focused on tuning (a few years ago?).
