Much like every other game they make? My favorite is still Europa Universalis. I like to start in 1400 as the Japanese with a goal of colonizing America first, and conquering Mecca, Jerusalem and Rome and converting them to the Shinto religion.
The passing in NHL11 is a lot different and sloppier. No more perfect passes every time. The hit physics can be amusing -- I had Toews brutalize Pronger behind the net once. I've seem dropped sticks, but not broken ones yet.
